JAF 5207-2RS Sealed Angular Contact Ball Bearing 35 x 72 x 27 mm
Available
This JAF range covers 12 double row angular contact ball bearings with two rubber seals (2RS): the 5302-2RS, 5303-2RS, 5304-2RS, 5305-2RS, 5306-2RS, 5207-2RS, 5307-2RS, 5208-2RS, 5308-2RS, 5209-2RS, 5210-2RS and 5211-2RS, from 15 to 55 mm bore and 42 to 100 mm outer diameter. Select the size from the drop-down: each size has its own bearing number and dimensions, speed and load ratings in the Model Details.
Angular contact bearings are built to carry radial load and axial load together. This double row type carries axial load in both directions from a single bearing, which saves space over a pair of single row bearings. The two rubber seals (2RS) keep dust and splashes out and hold the lubricant in.
Where this product is used
- Pumps, compressors and gearboxes
- Fans, blowers and small drive units
- Machinery where radial and axial loads act together on one shaft
Features
- Double row of balls in one bearing carries radial load and axial load in both directions, in less space than two single row bearings
- Two rubber seals (2RS) keep dust, dirt and splashes out and hold the lubricant in
- Limiting speeds 3,800 to 10,000 rpm, basic dynamic load ratings 12.75 to 55.90 kN and static load ratings 8.14 to 45.11 kN across the range

Selecting the right option
Rubber seals (2RS) give better protection against dust, dirt and splashes than shields and hold the lubricant in. Seals add friction, so a sealed bearing runs slower than an open or shielded bearing of the same size, and a high speed application is better served by a shielded bearing. The limiting speeds listed above are for these sealed bearings.
Fitting and use
Check the load against the figures for your size before ordering and apply a suitable safety factor. A double row angular contact bearing carries axial load in both directions, but heavy or one-sided thrust should be checked with AIMS before ordering.
Press on the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and through the outer ring in a housing.
Keep sealed bearings in their packaging until mounting and do not wash them.
