JAF 2206-2RS Sealed Self Aligning Ball Bearing 30 x 62 x 20 mm

This JAF range covers 6 double row self aligning ball bearings with two rubber seals (2RS): the 2305-2RS, 2206-2RS, 2306-2RS, 2207-2RS, 2208-2RS and 2209-2RS, from 25 to 45 mm bore and 62 to 85 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.

Self aligning ball bearings have a spherical outer ring raceway, so the inner ring and balls can swing to take up small angular misalignment between shaft and housing. They suit long shafts, shafts that deflect under load and housings that cannot be bored in line. The two rubber seals (2RS) keep dust and splashes out and hold the lubricant in.

Where this product is used

• Conveyor pulleys and idler rolls
• Fans, agricultural machinery and line shafting
• Shafts that deflect or housings that cannot be bored in line

Features

• Double row design with a spherical outer ring raceway, so the bearing tolerates small angular misalignment between shaft and housing
• Two rubber seals (2RS) keep dust, dirt and splashes out and hold the lubricant in
• Limiting speeds 4,600 to 6,500 rpm, basic dynamic load ratings 15.30 to 21.57 kN and static load ratings 4.66 to 7.26 kN across the range

Key specifications

Available sizes

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. Self aligning bearings carry radial load and a light axial load in either direction, and the misalignment they accept is small, so heavy axial loads and large deflections 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.
