Low friction torque (low torque) requirements typically arise in the following scenarios: Precision instruments and medical equipment (such as blood separators, diagnostic equipment, and laboratory sample handling equipment) require bearings to operate smoothly at low loads and high speeds, avoiding vibration or precision loss caused by friction; Industrial robot joints (wrists, elbows, etc.) require bearings that simultaneously meet load capacity, precision, rigidity, and low friction torque within limited space, ensuring smooth motion and repeatable positioning accuracy; Medical rehabilitation equipment (hospital beds, patient lifts, prosthetic joints) requires low friction and stick-slip-free motion to reduce wear and contamination risks; Dental and therapeutic equipment adjustment mechanisms similarly require low friction and quiet operation.
Thin-Section Four-Point Contact Ball Bearings
Designed specifically for industrial robot joints, with steel balls making four-point contact with the raceways, achieving high rigidity and low friction within limited space. Weight is only about 5% of standard bearings.
PTFE-Based Self-Lubricating Sliding Bearings (Bushings/Spherical Plain Bearings)
Using PTFE composite materials such as Turcite® and ELGOGLIDE®, they offer extremely low friction coefficients and require no external lubrication. Suitable for reciprocating motion and low-speed, high-side-load scenarios.
Engineering Plastic Sliding Bearings (iglidur Series)
Such as iglidur J, R, and JVSM, these offer extremely low friction coefficients under dry running conditions with minimal stick-slip effect. Suitable for medical equipment, automated machinery, and other scenarios requiring cleanliness and maintenance-free operation.
Thin-Section Crossed Roller Bearings
These combine the ability to withstand combined loads with low friction torque, commonly used in robot waist and wrist sections where high precision and smooth operation are required.
Hybrid Ceramic Bearings (Silicon Nitride Balls)
Silicon nitride balls are lighter than steel balls and produce smaller contact ellipses, reducing friction and starting torque. Suitable for applications requiring fine motion.
Hydrodynamic Bearings
By optimizing the inner diameter surface texture to form an oil film, they achieve low-friction, highly quiet operation. NTN Hydrodynamic BEARPHITE can achieve a minimum inner diameter of 0.6mm, suitable for medical equipment.
POM + α Sliding Layer Bearings (DAIBEST DBX01)
Friction coefficient of 0.01–0.15 under grease lubrication, maintaining low-friction smooth rotation during startup and low-speed, high-load conditions.
