Single row tapered roller bearings(With Metric Inch)
Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. The bearings are not self-retaining. As a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle (α). The size of the angle is indicated by the calculation factor e :the larger the value of e, the larger the contact angle. 
The LYNB standard range of single row tapered roller bearings covers the popular sizes of metric bearings manufactured to ISO 355:1977 and inch bearings which follow the ANSI/ABMA standard 19.2-1994. Single row tapered roller bearings are separable, i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup).A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. The range can be divided into bearings for general use and bearings with a flanged outer ring.
For bearing arrangements operating in particularly difficult environments, for example, where the lubricating oil may be highly contaminated, where high operating temperatures prevail or where heavy deforming loads can be expected, LYNB can supply particularly wear-resistant tapered roller bearings. Details are available on request.
▲   The design’s of all these tapered roller bearings are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
