BECO BJ17FC-2RS Heavy Series PTFE Lined Spherical Bearing, Sealed, 17 x 35 x 20 mm

BECO heavy series maintenance-free radial spherical plain bearings to DIN ISO 12240-1 series G carry heavy radial load while letting the shaft sit out of square, which is the job a rolling bearing cannot do. The series G envelope is wider and larger in outside diameter than the equivalent series E size, which gives a higher load rating on the same bore. The outer ring carries a PTFE sliding layer running against a hard chromium plated inner ring, so the joint runs dry, with no grease point and no relubrication schedule. That suits fixed-direction loads and any position where oil or grease is unwanted or cannot be reached.

It is sealed on both sides to keep dirt and water off the sliding surfaces. This range has 13 sizes with bores from 15 to 120 mm.

Where this product is used

Features

• Series G envelope: wider and larger in outside diameter than the equivalent series E size, for a higher load rating on the same bore
• Takes misalignment a rolling bearing cannot: the shaft can sit out of square
• PTFE sliding layer against a hard chromium plated surface: runs dry, with no relubrication
• Sealed on both sides to keep dirt and water out of the joint
• Built to DIN ISO 12240-1 series G 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.

PTFE lined joints suit steady, fixed-direction loads. For shock or alternating loads, the steel on steel type is the one built for it.

Fitting and use

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

PTFE lined bearings are maintenance-free and need no relubrication.

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