BECO BJ15E-2RS Spherical Plain Bearing, Sealed, 15 x 26 x 12 mm

BECO radial spherical plain bearings to DIN ISO 12240-1 series E carry heavy radial load while letting the shaft sit out of square, which is the job a rolling bearing cannot do. A hardened steel inner ring runs its spherical surface directly against a matching hardened steel outer ring, which gives this type very high static load capacity and tolerance of shock and alternating loads.

It is sealed on both sides to hold the grease in and keep dirt and water out. Steel on steel joints need periodic greasing, so plan it into the service schedule. This range has 26 sizes with bores from 15 to 300 mm.

Where this product is used

• Hydraulic and pneumatic cylinder eye ends
• Construction and earthmoving linkages
• Agricultural implements and three-point linkage
• Materials handling and conveyor pivots
• Crane and loader articulation
• General engineering joints that swing or oscillate under load rather than rotate continuously

Features

• Takes misalignment a rolling bearing cannot: the shaft can sit out of square
• Hardened steel on hardened steel sliding surfaces, for high static load capacity and tolerance of shock and alternating loads
• Sealed on both sides to keep dirt and water out of the joint
• Built to DIN ISO 12240-1 series E boundary dimensions

Key specifications

Available sizes

Selecting the right option

Select by bore d first, then check the outside diameter D, ring width and sphere diameter dK in the table against the housing and the mating part.

Dynamic and static load ratings are not listed on this page. Contact AIMS Industrial to confirm ratings against your application before ordering.

The misalignment angle shown is the nominal series figure. Check it against the movement the joint has to take.

Steel on steel suits shock and alternating loads and needs periodic greasing. Where the joint cannot be greased, choose a PTFE lined bearing.

Fitting and use

Press only on the ring being fitted, and never through the sliding surfaces of the joint.

Grease the bearing at the service interval for your duty. The seals hold the grease in but do not remove the need for periodic greasing.

Contact AIMS Industrial for help choosing the fit and the service interval for your application.
