BKZ Industry manufactures and supplies plastic rolling bearings, plastic bushings, plastic thrust washers, plastic bearing units, and custom plastic bearings. Products are available in fully plastic and hybrid constructions, with both standard models and custom dimensions supported.
Plastic ball bearings use rolling elements with a small contact area to provide smooth, low-friction rotation. Compared with plastic roller bearings and many plastic bushings of similar size, they are generally better suited for higher-speed, light- to medium-load applications.
Types:
Deep-groove Ball Bearings
Angular-contact Ball Bearings
Thrust Ball Bearings
Self-alining Ball Bearings

Temperatue Range: Approx. −250°C to +260°C, depending on material
Applications: Chemical processing, food and medical equipment, marine systems, electrical insulation, and high- or low-temperature environments
Plastic roller bearings use line contact between the rollers and raceways, providing higher radial load capacity and rigidity than plastic ball bearings of a similar size. Plactic roller bearings are customized options based on customer requirements.
Types:
Cylindrical Roller Bearings
Tapered Roller Bearings
Product Details:
Engineering plastic bushings are made from wear-resistant composite materials and can operate without oil or grease. Compared with ball bearings and roller bearings, plastic bushings are cheaper in cost and much easier to install.
Types:
Sleeve Bushings
Flanged Bushings
Thrust Washers
Product Details:
Sizes: Standard and custom sizes available
Material Options: POM, Nylon PA, PET, PEEK, PI, PPS, PTFE, PVDF, and modified polymer composites
Temperature Range: −100°C to +250°C, depending on material
Lubrication: Self-lubricating, dry-running, and maintenance-free
Applications: Food and packaging machinery, chemical equipment, water systems, automotive equipment, and general industrial machinery
Plastic insert ball bearings are designed to fit mounted bearing housings, making installation and replacement easier. Plastic raceways and cages combined with stainless steel, ceramic, glass, or plastic balls provide low-friction, lubrication-free operation in wet and corrosive environments.
Product Details:
Sizes: Standard UC series
Raceway Materials: POM, HDPE, PP, UPE, PTFE, or PVDF
Ball Materials: Glass, stainless steel, or ceramic
Cage Materials: POM and other engineering plastics
Load Capacity: Light to medium radial loads and limited axial loads
Temperature Range: Approximately −150°C to +260°C, depending on the raceway and ball materials used.
Applications: Food processing, packaging, washdown equipment, chemical systems, marine equipment, conveyors, and more
Plastic bearing units combine a thermoplastic housing with an insert ball bearing. They are lightweight, corrosion-resistant, easy to install, and maintenance-free, while also providing good shock and vibration absorption.

BKZ Industry understands the importance of consistent quality, stable supply, and on-time delivery. We provide reliable support at every stage to ensure plastic bearings reach customers smoothly and on schedule.
BKZ Industry operates dedicated production lines for plastic bearings, helping maintain stable production capacity and consistent supply. We can arrange production according to customer requirements, including bearing type, size, material, quantity, and delivery schedule.
Different bearing types and models can be combined in one order. Trial orders are also supported, allowing customers to test product suitability before placing bulk orders.
We inspect bearing dimensions, roundness, concentricity, clearance, and other key parameters. Inspection reports can be provided with the order upon request.
BKZ Industry operates under an ISO 9001:2015-certified quality management system to maintain controlled production processes and consistent product quality.
With over 15 years of bearing manufacturing and export experience, BKZ Industry supports customers with production, documentation, packaging, shipping, and international order delivery.
Consider the bearing type, load, speed, motion, operating temperature, chemical exposure, moisture, shaft material, dimensions, and food-contact or electrical requirements. Provide these operating conditions to us to get the quotation.
An engineering plastic bushing is a plain bearing made from an engineering polymer or polymer composite. It has no balls or rollers and supports rotating, linear, or oscillating motion through sliding contact. Many designs are self-lubricating and suitable for dry operation.
A plastic bushing is one type of plastic bearing. It uses sliding contact and has no rolling elements. The term plastic bearing is broader and includes plastic bushings, ball bearings, roller bearings, insert bearings, and mounted bearing units.
POM bearings are economical, wear-resistant, dimensionally stable, and suitable for general-duty applications at moderate temperatures. PEEK bearings provide higher temperature resistance, mechanical strength, chemical resistance, and load capacity, but are more expensive.
Yes. PPS and PI are commonly used for high-temperature plastic bearings. PPS generally offers continuous operating temperatures of approximately 200–230°C, while some PI grades can operate continuously at approximately 250–290°C. Actual limits depend on the material grade, load, speed, and bearing structure.
Food-contact-compliant grades of PEEK, PTFE, POM, PP, and UHMW-PE can be used for food-processing equipment. Stainless steel or ceramic rolling elements may also be selected. The specific material must have the required FDA, EU, or other food-contact documentation for the intended application.
Plastic bearings are one of the many bearing types supplied by BKZ Industry. Other available bearing types include:
