GEFZ C Inch PTFE Composite Spherical Plain Bearings
GEFZ C is an inch-size self-lubricating range with a PTFE composite sliding layer. The full table retains original metric and inch dimensions.
Description
The GEFZ C source identifies steel/PTFE composite sliding contact and refers its construction to the GE C range, with inch dimensions.
The catalogue lists -50°C to +150°C. Dynamic and static ratings are reproduced independently for each designation, alongside ring widths and installation radii.
Construction and configuration
- Sliding pair
- Steel/PTFE composite
- Materials
- Steel rings; construction referred to GE C in the source
- Catalogue temperature range
- -50°C to +150°C
C denotes the composite-lined range here. The GEFZ T fabric-lined and GEFZ S steel-on-steel ranges have separate material descriptions and 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.
