Import Elevator Roller — Buy in Bulk from Supplier in China

The Elevator Roller is a precision-engineered component used in elevator guide systems to reduce friction and ensure smooth car movement. It consists of a steel shaft with a polyurethane or nylon wheel, mounted in a sealed bearing housing. This design minimises noise and wear during repeated operation over thousands of cycles. The roller is compatible with standard elevator guide rails and is suitable for both traction and hydraulic systems.

The wheel material is either high-density polyurethane with a shore hardness of 85A or engineered nylon 66, chosen for low friction and resistance to abrasion. The shaft is made from cold-drawn carbon steel, hardened to HRC 50-55, and coated with zinc-nickel for corrosion resistance. Typical tolerances for wheel diameter are ±0.1mm, and shaft concentricity is held to 0.02mm. These specifications align with industry norms for mid- to high-rise elevator installations.

This component is primarily sourced by elevator manufacturers, maintenance contractors, and component distributors in Asia and the Middle East. Buyers typically order in quantities of 100 to 500 units per shipment for use in new builds or retrofit projects. Packaging is in corrugated cartons with foam inserts, and bulk orders are palletised. Trade terms are usually FOB Tianjin, with lead times of 14 to 21 days after deposit. Custom bore sizes or wheel materials are available for OEM projects.
