GEFZ T Inch PTFE Fabric Spherical Plain Bearings
GEFZ T inch bearings have a PTFE fabric sliding layer in a formed carbon steel outer ring. Both catalogue unit rows are preserved.
Description
The GEFZ T range uses PTFE fabric bonded to the outer-ring spherical surface. The outer ring is carbon steel formed around the bearing assembly.
The inner ring is hardened bearing steel with a hard-chromed spherical surface. The listed temperature range is -50°C to +150°C.
Construction and configuration
- Sliding pair
- Steel/PTFE fabric
- Materials
- Formed carbon steel outer ring with PTFE fabric; hardened bearing steel inner ring
- Catalogue temperature range
- -50°C to +150°C
Keep the T fabric designation distinct from GEFZ C composite and GEFZ S steel-on-steel products. Similar outside dimensions do not establish equal ratings.

Information for your enquiry
Include the complete designation, quantity, mating dimensions or thread, load direction, motion and operating environment. Specify lubrication access and the seal arrangement where relevant. Catalogue dynamic and static ratings are different quantities; neither is an application-specific working-load or life guarantee.
Can I use another material or thread?
State the required configuration and drawing. Additional left-hand, material or sealing options need a confirmed full designation and are not generated automatically from the listed models.
What if a dimension is missing?
Request the current drawing for the selected designation. Blank values are retained from the source and are not filled from adjacent models or another series.
For a drawing-defined part or changed interface, see our custom bearing enquiry options.
