This page is built for the maintenance engineer holding a stamped number and a stopped machine: compressor bearing grades sourced through our network of roller bearing manufacturer partners and held as ready stock, paired with a working air compressor bearing manufacturer cross-reference so a legacy or superseded part number still converts into a quote on the same working day. The anchor SKU here is BVN-7160, a combined cylindrical roller and angular contact unit measuring 94.9 x 170.2 x 43 mm, weighing 7.00 KG and stated as Made in Austria, with 75 sets on the shelf.
The reason a compressor rotor does not simply run on two ordinary bearings is load direction. Before you compare numbers, it helps to know what the part is being asked to do.
A screw or reciprocating compressor rotor is loaded in two directions at once. The rotor and its gears generate sustained radial force as the shaft spins and the lobes mesh, while discharge pressure and timing-gear thrust push the shaft along its own axis. A single cylindrical roller bearing handles the radial load comfortably but offers almost no axial capacity; a pair of deep groove ball bearings tolerates some thrust but gives up radial stiffness.
The combined design solves this by housing two element types in one envelope. The cylindrical roller row carries the radial load across its line contact, and the angular contact ball row takes the axial load through an angled raceway. Buying them as one unit instead of two separate assemblies removes the need for an extra bearing block, shortens the shaft, and reduces the number of fits and tolerances a maintenance team has to control at rebuild.
Practically, that matters at three points: assembly time at rebuild, the number of spare part numbers a plant must keep on the shelf, and the accuracy with which the rotor sits in its housing. Where a compressor runs near-continuously, bearing replacement is usually the trigger for the whole service window, so a unit that arrives as one pre-set part compresses that window.
The cylindrical roller row carries the sustained radial force created by rotor rotation and gear mesh through full line contact.
The angular contact row takes thrust from discharge pressure and timing gears through its angled raceway geometry.
A combined unit replaces separate bearing blocks, so fewer fits and tolerances need to be controlled during a rebuild.
Stores hold one SKU rather than two matched components, which simplifies procurement and reorder planning.
Everything on this page routes back to one bearing that is confirmed in stock. Here is what a buyer is actually committing to.
BVN-7160 is listed as a cylindrical roller bearing and angular contact ball bearing combined bearing for air compressors. Its application field names Atlas air compressor equipment, and the unit is described as a compact solution for maintenance replacement as well as OEM integration into new rotor and shaft assemblies.
The headline dimension reads 94.9 mm bore, 170.2 mm outer diameter and 43 mm height, with 7.00 KG per unit. The page title and URL express the same envelope as 95 x 170 x 43. That gap is dealt with in the fitment module below, because it changes how you measure a worn part.
If your application is an Atlas compressor rebuild and the worn part stamps BVN-7160, this is a direct replacement path with 75 sets on hand. If you are specifying for a different compressor brand or a new rotor design, request the drawing confirmation first rather than assuming dimensional interchangeability.
Compressor bearing enquiries arrive in four recognisable shapes. Each one needs a different piece of information before a quote can be firm.
Confirmed fields for the stocked SKU. Where the source material does not publish a value, the row is left open rather than estimated.

If your spares list shows a number that no longer appears on an order sheet, one of these pairs is usually the reason. The anchor row shows the number that is actively stocked.
Four routes to a confirmed number. Use whichever your site allows, and include the result in the quote request.
The fastest route. Check the outer ring face and the box label, and photograph both before the part is disposed of — the number is easier to read while the bearing is intact.
Bore sets the shaft fit. For a 94.9 mm nominal, measure the worn inner ring at several points; a bearing removed after a long service life will read slightly different from new.
Outer diameter fixes the housing fit and height confirms the shoulder position. Take outer diameter across the ring and height across the full assembled unit.
Where the bearing is unmarked, the compressor model and serial number are enough to work back to the intended position and nominal size.
The questions that stop an enquiry from turning into an order, answered in one place before you write.
BVN-7160 is listed as ready to ship with fast delivery against 75 sets of stock. For other numbers, lead time depends on whether the item is on the shelf or brought in.
No minimum order quantity is published for this SKU. Single-unit replacement and repeat production volume both go through the same quote process.
At 7.00 KG per unit, packing and freight are planned around quantity. State the destination and required date so the shipping method can be quoted with the bearing.
Terms are confirmed on the quotation. Corporate and repeat accounts can discuss terms when the enquiry states the purchasing arrangement.
For OEM evaluation, request the part you intend to test and describe the assembly it goes into, so the correct position is confirmed rather than assumed.
Stock is described as 100% genuine and new. Warranty wording is confirmed with the quotation; nothing here should be read as an unstated guarantee.
Give us the stamped number, the compressor model or the measurements you have taken, and the quantity you need. We confirm the SKU, the origin and the delivery position, then send pricing. If you are buying for production rather than repair, say so and include your annual volume so the sourcing terms match the order.

View productit is a combined bearing that merges a cylindrical roller bearing with an angular contact ball bearing in a single unit, intended to carry radial and axial loads together. the application field on the product page names atlas air compressor equipment, covering both maintenance replacement and oem integration into new rotor and shaft assemblies.
both describe the same bearing. the page title and url use the rounded 95 x 170 x 43 form, while the published specification fields state 94.9 mm bore and 170.2 mm outer diameter with a 43 mm height. treat the decimal figures as the specification value and the round numbers as the nominal label.
the product page lists 75 sets in stock and states that the item is ready to ship with fast delivery. stock moves, so the current quantity is confirmed at the point of quotation rather than assumed from the published figure.
no. origin is stated per sku, and bvn-7160 carries a stated manufacturer origin of austria. this page is a stock and cross-reference resource: bearings are supplied to manufacturer-grade specification and held as ready stock. the origin field tells you where the bearing was made, not who is selling it.
use the cross-reference block on this page. paired numbers such as np658549 with np104948, np645406 with np182140 hc, and np804861 with np914811 indicate that one reference has been superseded by another. send the stored number and the compressor model, and the current equivalent is confirmed before you order.
those values are not published on the product page, so they are confirmed on enquiry rather than stated here. send the position the bearing sits in and the information you need, and the technical detail is provided as part of the quotation process.
