Product Description

81128 M brass Cage Thrust Roller Bearing For High Power Marine Gear Box

Standards
Axial cylindrical roller bearings according to DIN 722 (series 811 and 812) The versions 813, 814, 874, 893, and 894 are not standardied.

Tolerances
Running, design and dimension tolerances of axial cylindrical roller bearings are equivalent to the axial bearings standard tolerances, see section bearing data. Axial minimum load Axial cylindrical roller bearings have always to operate under axial load to avoid any slip between rollers and bearing washers. If external load is too small, you may use springs to achieve a pre-stress of the bearing. The minimum axial load is calculated as follows:

F_a min minimum axial load [kN]

C₀ static bearing capacity [kN]

n maximum operating speed [min^-1]

k_a factor, see table

Series	factor ko
811	1,4
812	0,9
813	0,7
814	0,4
893	0,7
894	0,5

Cages

Axial cylindrical roller bearings come with machined brass cages. Our favourite is the roller guidance version, letter code M. It is possible to deliver the versions MB and MPB (cage supported on a disc washer).

Equivalent dynamic load

P = F_a [kN]

Equivalent static load

P₀ = F_a [kN]

Product Description

The roller and raceway surface of Cylindrical Roller Bearing is line contact, so the bearing has high carrying radial load capacity, applicable to carrying heavy load and shock load.Besides, owing to its structure, it's easy to high accuracy processing, applicable to high rate rotary.Inner ring and outer ring are separable, convenient for mounting and dismountin.
