- Industrial distributors sourcing plastic roller bearings in volume
- Manufacturers of gravity rollers, sprocket rollers, and O-belt rollers
- Production line builders requiring low-noise, free-running roller components
Problems It Solves
- Inconsistent roller performance due to poor bearing fit in standard tube sizes
- Noise and vibration from non-precision bearings in gravity roller systems
- Corrosion or wear in metal bearings when used with PVC or stainless steel tubes
- Difficulty in aligning rollers when the bearing does not match the shaft and tube dimensions
- Need for a single source of matched plastic roller bearings for multiple roller types
Technical Features

- Housing made from plastic or nylon material for lightweight and chemical resistance
- Designed specifically for 30 mm tube diameter with 1.5 mm or 1.8 mm wall thickness
- Shaft diameter of 10 mm ensures secure fit and alignment with the roller shaft
- Free running design reduces friction and effort during product movement
Materials
- Plastic housing for lightweight and non-corrosive use
- Nylon housing for improved wear resistance and durability
- Precision bearings integrated into the housing for consistent rotation
- Compatible with steel, stainless steel, and PVC tubes
- Suitable for washdown and clean environments due to non-metallic construction
Quality Control
- Bore size verified to match the 10 mm shaft diameter
- Precision bearing checked for free rotation and smooth movement
- Housing dimensions confirmed against 30 mm tube diameter and 1.5 or 1.8 mm wall thickness
- Material grade confirmed as plastic or nylon based on order specification
Customization Options
- Special bore sizes available upon request for large quantity orders
- Alternative housing materials possible based on volume and application
- Custom model numbers available for specific tube and shaft dimensions
- Adjustments to wall thickness or tube diameter can be considered for bulk production
Use Guide
- Ensure the tube diameter is 30 mm and wall thickness is 1.5 mm or 1.8 mm before installation
- Verify the shaft diameter is 10 mm to match the bearing bore
- Use the correct model (KTR-30X1.5-10 or KTR-30X1.8-10) based on wall thickness
- Install with the housing aligned to the tube to prevent binding
- Avoid overloading beyond the intended application load to maintain bearing life
