Roller
Three-Point Contact Full Ball Bearing Roller
As the flagship product of Sambon Precision Co., Ltd., the three-point contact full ball bearing roller has been trusted for over 25 years. It is widely used as a guide roller in kimchi refrigerator drawers, sliding doors, and automobile consoles, earning a reputation for reliability and performance.
Unique Design and Features
This innovative roller features a triangular contact design, with three points of contact between the balls and the counterpart. Unlike standard bearings with two points of contact and a cage, ORBIS’s full-ball design offers:
Higher Load Capacity
: Handles greater loads compared to standard bearings of the same size and material.
Twist Resistance
: Ensures smooth operation and durability, even with misaligned counterparts.
Breaking Load Advantage
: Provides greater breaking load strength for demanding applications.
While ideal for low-speed movements under 300 RPM, this roller is perfectly suited for drawers, doors (folding, sliding, flat), and rail guides.
Cost-Effective Manufacturing and Customization
ORBIS’s in-house automated production facilities ensure:
Stable Supply
: Reliable delivery, even for large orders.
Competitive Pricing
: Cost-effective solutions without compromising on quality.
Custom Options
: Standard rollers feature acetal (POM) outer rings and integrated shafts. A high-load version with steel outer rings is under development to meet customer requests for enhanced durability.

Main Features
1. Smooth Operation
Manufactured using specially annealed polyacetal (POM) round-bar, ORBIS outer rings ensure excellent roundness, minimal deformation, and smooth performance.

Precision-machined outer rings and inner rings made with super-precise presses ensure consistent performance, even during extended use.
(Refer to factory durability tests for details.)

Alloy-plated shafts and 420J2 stainless steel balls make these rollers highly resistant to corrosion, ensuring longevity and cleanliness in humid environments.
(Refer to factory corrosion-resistance tests for details.)
4. Customizable Outer Ring Shape
Unlike injection-molded designs, machined POM outer rings allow for small-scale production of special shapes, reducing part count and simplifying related designs.
5. Reasonable Pricing
Press-machined inner rings, forged shafts, and fully automated mass production processes enable ORBIS to provide high-quality rollers at a competitive price.
6. Quality Assurance
Every roller undergoes a rolling test before packaging, ensuring consistent quality and reliability for our customers.
