Pulley bearing ring refers to the ring structure component installed on the inner and outer ring of pulley bearing, and its main function is to support and fix the rolling element to ensure the smooth operation of the bearing. FTM customizes pulley bearing rings in different sizes to meet customer needs.
Pulley bearing rings have the following functions:
Support and fixation: the ring can support the rolling element of the bearing, maintain the smooth movement of the rolling element, and ensure the correct coordination of the inner and outer rings.
Reduce friction: the ring can effectively reduce friction when running, so that the pulley bearing in the high speed, heavy load environment to maintain smooth operation, extend the service life, FTM will have high precision (P2,P4), to make the ring more matching the bearing, to further reduce friction.
Protection: The ring can help prevent dust, impurities, etc., from entering the bearing interior, thereby protecting the rolling element and raceway to avoid wear and failure.
Improve the load capacity: through the reasonable design of the ring structure, can improve the bearing capacity, so that it is more suitable for heavy load environment, FTM will choose the appropriate material (bearing steel, Gcr15, 45 steel, etc.) to ensure the bearing capacity of the ring.
Size Processing range: diameter 10mm-250mm

A Pulley Bearing Ring is a foundational structural component integrated into the inner or outer raceway assembly of a pulley bearing. Its primary and critical role is to support and precisely fix the rolling elements, ensuring the bearing operates with optimal stability, reduced friction, and extended service life. FTM specializes in the customization of these rings in a wide range of sizes, guaranteeing a perfect fit for diverse customer applications.
Our custom pulley bearing rings are engineered to deliver measurable performance benefits:
Our ability to provide high-quality bearing solutions stems from our core strengths:
Q: What is the main difference between FTM's P4 precision rings and standard rings?
A: P4 (ABEC 7) rings feature tighter dimensional tolerances, better geometry, and smoother finishes. This results in lower friction, less vibration, and a longer service life compared to standard P0/P6 rings.
Q: What non-standard features can FTM customize besides size and material?
A: We customize raceway profile geometry (e.g., V/U-groove), internal/external features (e.g., mounting holes), heat treatment specifications, and specialized surface coatings.
Q: Which core industries most benefit from high-precision pulley bearing rings?
A: Industries requiring high reliability and speed, particularly textile machinery, high-speed automation equipment, and heavy-duty engineering machinery.
Q: What is the typical lead time for a customized batch?
A: Lead time generally ranges from 4 to 8 weeks after final design confirmation. This varies based on complexity, material, precision grade, and order volume.
Q: What is the target surface hardness for your GCr15 bearing steel rings?
A: Following heat treatment, we target a high surface hardness of 60-64 HRC (Rockwell Hardness C scale) to ensure maximum wear resistance.
