ZOTY Bearings : POM and Nylon Rollers for Sliding and Automatic Doors
Door-system roller components for OEMs and replacement-part buyers.
Source POM and Nylon (PA) bearing rollers for sliding-door and automatic sliding-door projects. Start with the track profile, mounting arrangement and required material, then send your drawing or sample details for model review.
Request a quotation & model reviewBSU62630-10 POM U-groove roller reference. Track compatibility and load require project-specific confirmation.
Sliding doors and automatic doors
Sliding-door rollers: match the wheel contact profile to the rail and confirm how the roller is mounted and retained.
Automatic sliding-door roller components: provide the operator or hanger drawing, door weight, number of rollers, opening speed and operating cycles. We review the component fit for your assembly.
Replacement parts: send the original wheel, bearing marking, groove profile and mounting details. A similar-looking wheel is not sufficient to establish compatibility.
This page covers roller and bearing components. Long-shaft garage-door rollers, complete door operators, motors and control systems are outside this selection.

Nylon (PA) is listed among our roller material options. The two reference models above specify POM in their technical descriptions. A mixed POM/Nylon product title does not mean those models have a confirmed Nylon configuration.
There are many available sizes. Send your required outside diameter, width, bore and groove or mounting drawing for review instead of selecting solely by a broad size range.
Confirm POM or Nylon material for the required model. The selected references use built-in deep groove ball bearings and list rubber-seal or metal-shield options. Confirm the complete bearing marking, closure and lubrication for your order.
For a bore-mounted wheel, provide the axle fit, spacers, retention and clearance. For a screw-mounted wheel, provide thread specification, screw length and the shoulder or bracket drawing. Match groove depth, angle and contact surface to the rail.
Customization and project limits
Illustrative roller options. Feasibility is reviewed against the selected material, model and drawing.
Our roller range supports drawing-based review of wheel size, profile, groove, color, bearing and mounting options. Ask for the specific Nylon or POM configuration you need. Samples and non-standard changes require confirmation.
No door-weight, load per roller, speed, cycle-life, temperature or noise rating is assigned to these references here. Provide the load distribution and operating conditions for review. Catalogue application examples do not establish compatibility with every automatic-door brand or hanger.
