Plastic Taper Sleeve Roller
The 05WR is a plastic taper sleeve roller with a precision bearing housed in a nylon and PP casing. It fits over a steel tube with a diameter of ø12 mm and has a tapered sleeve that matches a 3.6 degree taper. The small end diameter is D1 = ø56 mm, and the big end diameter is D2 = E = W + 9 mm. The roller length is L = W + 11 mm, and the total length is 8X12 mm. It is designed for use on steel tubes in conveyor systems where a consistent fit and low-friction rotation are required.
Product Overview

Part of the Roller range, used in Warehouse and Distribution Centres.
Key Benefits
- Precision bearing ensures smooth rotation under load
- Nylon and PP casing reduces weight and resists wear
- Tapered sleeve fits over ø12 mm steel tube with 3.6 degree taper
- Small end diameter D1 = ø56 mm, big end diameter D2 = E = W + 9 mm
- Roller length L = W + 11 mm, total length 8X12 mm
- Steel tube provides structural support for the roller assembly
Application Scenarios
- Conveyor lines where rollers must fit precisely over a standard ø12 mm steel tube
- Assembly lines requiring low-friction rotation with consistent alignment
- Material handling systems using tapered sleeves to maintain roller position
- Belt conveyors where roller end alignment affects belt tracking
- Light to medium load applications where plastic casing reduces noise and wear
Who It Is For
- Conveyor system integrators building roller conveyors with standard tube sizes
- Industrial equipment builders needing consistent roller fit on steel tubes
- Warehouse automation contractors installing rollers on existing tube frames
- Production line builders requiring precise roller alignment without adjustment
- Industrial distributors stocking rollers with defined taper and tube fit
Problems It Solves
- Rollers that wobble or misalign due to poor fit on standard steel tubes
- Inconsistent roller height caused by mismatched sleeve diameters
- Frequent bearing failure from poor housing support or material mismatch
- Difficulty in mounting rollers on tapered tube ends without custom machining
- Lack of standardization in roller fit across different suppliers
Technical Features
- Precision bearing housed in nylon and PP casing for low friction and wear resistance
- Tapered sleeve with 3.6 degree taper fits over ø12 mm steel tube
- Small end diameter D1 = ø56 mm, big end diameter D2 = E = W + 9 mm
- Roller length L = W + 11 mm, total length 8X12 mm
- Steel tube provides rigidity and load support for the roller assembly
- Casing material (nylon and PP) reduces weight and noise during operation
Materials
- Nylon and PP casing for lightweight, wear-resistant housing

Quality Control
- Taper angle verified against 3.6 degree specification
- Fit on ø12 mm steel tube checked for proper engagement
- Bearing rotation tested for free movement
- Casing dimensions confirmed against D1, D2, L and total length
- Final inspection of assembled roller for alignment and fit
Customization Options
- Tapered sleeve available in 3.6 degree angle for ø12 mm tube
- Casing material (nylon and PP) standard, no alternative options listed
- Steel tube standard, no alternative tube material listed
- Roller length L = W + 11 mm, total length 8X12 mm, no variation listed
Use Guide
- Ensure the steel tube diameter is exactly ø12 mm before mounting
- Verify the taper angle is 3.6 degrees to match the sleeve
- Check that D1 = ø56 mm and D2 = E = W + 9 mm for correct end diameters
- Confirm L = W + 11 mm and total length 8X12 mm for proper fit in the frame
- Install the roller by sliding it onto the tube with the taper aligned
