Taper Roller Bearing Single Row 30317, 85mm Bore
Ntn Tapered Roller Bearings
The Ntn Tapered Roller Bearings adopts CAD design and adopts advanced processing equipment and manufacturing processes including intermediate frequency hot forging and expansion forging, numerical control multi-knife, and profiling turning, heat treatment for protection atmosphere, numerical control grinding, and automatic grinding processing line production; the detection means are complete. Dynamic and non-destructive testing of the product's shape profile, roundness, roughness, vibration, noise, cracks, life, etc., and the effective operation of the TS16949:2002 and ISO9001:2000 quality systems ensure that the entire process quality is controlled.
Package: Usually made by plastic tube+anti-rust paper+box+carton
Terms of Payment: T/T(30% deposit in advance), Irrevocable L/C at sight, Western Union
Delivery Time: 3-25 days, according to the order quantity
Feature:
High load carrying capacity
The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
Amisalignment
Tapered roller bearings are self-aligning and can accommodate misalignment .
Separable design
Tapered roller bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.
High speed capability
The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
Long service life
The tapered roller profile reduces edge stresses at the roller/raceway contact.
Low friction
The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.
