305802C-2Z Cam Roller Bearing

The 305802C-2Z is a double-row cam roller bearing with a 15 mm bore, 40 mm outside diameter, and 15.9 mm width. It is designed for cam-driven and track-guided mechanisms where a rotating roller runs against a cam or guide surface.

This EKB version uses a double-row ball design with a polyamide (nylon) cage. The outer ring has a crowned (convex) profile, which helps compensate for minor misalignment and reduces edge loading at the contact area.

The 2Z configuration uses steel sheet shields on both sides, with a small clearance gap between the shields and the inner ring shoulder — the standard arrangement for this type. The bearing is filled with grease at the factory.

Our 305802C-2Z is an independently manufactured replacement bearing. The designation and reference number 14216298001124 are provided for identification and cross-reference purposes only.

Product Specifications

Note: Confirm the complete dimensions and technical specifications against the supplier's drawing before ordering or replacing an existing bearing.

Key Features

• Double-Row Ball Design
  Two rows of balls provide the load-carrying arrangement for this compact cam roller, within the bearing's design limits.

• Crowned Outer Ring
  The crowned (convex) outer ring profile helps compensate for minor misalignment and reduces edge loading where the roller contacts the cam or track surface.

• Polyamide Cage
  The polyamide (nylon) cage is commonly used in this type of cam roller for its combination of low weight and good sliding characteristics.

• 2Z Steel Shields
  The 2Z configuration uses steel sheet shields with a small clearance gap between the shields and the inner ring shoulder — the standard arrangement for this design.

• Grease-Filled
  The bearing is filled with grease at the factory for ready-to-fit operation.

• Specification-Based Replacement
  When replacing an existing 305802C-2Z, check the complete dimensions and design rather than matching the model number alone. Differences in cage, sealing, or clearance may affect interchangeability.

Measured Dimensions & Quality Verification

Every 305802C-2Z supplied by EKB is 100% dimensionally inspected before shipment.

The measured dimensions of each bearing are verified to be within the tolerance ranges specified by the national standard (GB/T). Actual measurement data and the dimensional drawing are available on request.

Typical Applications

Cam rollers of this size are commonly used in:

• Cam-driven mechanisms

• Small conveying and indexing equipment

• Packaging machinery

• Textile and printing equipment

• Guide and support rollers in compact assemblies

• Other applications requiring a small crowned cam roller

Actual suitability depends on load, speed, temperature, shaft and housing fit, and the operating environment.

Dimensions and Replacement Compatibility

The basic dimensions of 305802C-2Z are:

• Bore: 15 mm (0.591")

• Outside diameter: 40 mm (1.575")

• Width: 15.9 mm (0.626")

• Fillet radius: 0.6 mm (0.024")

Other important details include the crowned outer-ring profile, cage type, sealing arrangement, clearance, and lubrication.

A bearing with the same bore, outside diameter, and width is not necessarily an interchangeable replacement.

If you are replacing an existing bearing, please send the original part number, dimensional drawing, photographs, or a physical sample. EKB can help check the available specification before an order is placed.
