Gravity Roller Metal Bearings
The MTR-57X1.2-12 to MTR-63.5X2.5-15 series are gravity roller metal bearings designed for tube diameters of Φ57, Φ58, Φ59, Φ60, and Φ63.5 mm. Each unit is built with a precision bearing and a metal housing to support free-running operation on gravity roller systems. They are used in conveyor lines where consistent shaft alignment, load capacity and smooth rotation are required. The bearings are available in multiple bore sizes and lengths to match standard roller tube dimensions. They are suitable for use in industrial environments with medium to heavy load applications.

Problems It Solves
- Inconsistent roller end cap fit on standard tube diameters leading to misalignment and binding
- Lack of matched bearing and housing combinations from multiple suppliers causing assembly delays
- Rollers that bind or rotate unevenly due to poor bearing fit or housing tolerance
- Need for custom parts when standard end caps do not match existing tube and shaft sizes
- Frequent replacement of bearings due to low durability in high-load or repetitive motion environments
Technical Features

- Available in multiple bore sizes and lengths to match standard roller tube dimensions
- Metal housing provides structural stability and resistance to deformation under load
- Bore size and length options allow direct fit on existing roller shafts without modification
Materials
- Metal housing for structural integrity and resistance to deformation under load
- Precision bearing material designed for low friction and long service life
- Bore and shaft interface engineered for direct fit on standard roller tubes
Quality Control
- Bearing rotation tested by hand to confirm free movement without binding
- Housing dimensions checked against bore and length specifications
- Model number verified against order before packing
- No defects in metal housing or bearing surface visible upon inspection
Customization Options
- Special bore sizes available upon request for large quantity orders
- Length and bore combinations can be adjusted to match specific tube and shaft requirements

Use Guide
- Match the model number to the tube diameter and shaft size of your existing roller
- Ensure the bore size and length match the shaft and roller end cap dimensions
- Use the correct model to prevent misalignment and binding during operation
- Select the appropriate length based on the roller end cap depth and shaft protrusion
- Verify the bearing rotates freely before installing into the roller system

Compared With Other Options
| Plastic roller bearings | Metal bearings offer higher load capacity and durability in heavy or repetitive use, while plastic is lighter and quieter |
|---|---|
| Pressed-in end caps | These metal bearings are designed for direct fit and can be replaced without removing the entire roller, unlike pressed-in types |
| Standard off-the-shelf bearings | These are sized specifically for common gravity roller tube diameters, reducing the need for custom machining |
