The Sbr Linear Guide rail embodies a precise linear motion configuration employing the rolling friction concept. It consists of a sturdy aluminum alloy support structure and a toughened, chrome-plated smooth shaft, operating with great efficiency. By allowing the uninterrupted rolling of steel balls between the glide and the guide rail, it aids in achieving high-precision linear movement of the load platform. Boasting a friction coefficient that is just 1/50 of traditional sliding guide rails, it exhibits exceptionally low initial friction, thereby significantly improving the positioning precision and operational effectiveness of the equipment.
product highlights
Ultra-high precision, accurate positioning
Rolling friction design:The point contact structure between the steel balls and the guide rail effectively reduces the friction resistance, and the positioning accuracy can reach ±0.01mm.Dedicated
Low backlash characteristics: The difference between dynamic and static friction forces approaches zero, avoiding the "slipping" phenomenon and ensuring the stability of the repeated positioning accuracy.
Long service life and high reliability
High-quality Materials: The guide rail is made of 45# steel or GCr15 bearing steel. The surface hardness after quenching reaches HRC58 - 62°, the wear-resistant layer thickness is 0.8 - 3mm, and the anti-fatigue life is increased by more than 3 times
Impact-resistant Structure: The core part has a low hardness (HRC30 - 40°), which can absorb vibration impacts and reduce equipment resonance.
Flexibly adaptable, easy to install and maintain
Modular Design: Supports multi-slider combinations and cutting to any length (up to 6 meters), adaptable to complex mechanical structures
Lubrication-free Technology: Features an internal oil storage block design, enabling 6 months of maintenance-free operation; also supports an automatic oil supply system to reduce manual intervention.
