GZB roller heavy load linear motion guide is consisted of rail, block, roller, re-circulator, retainer, roller cage and seal gasket etc.
◆ Heavy load
a、Line contact instead of traditional point contact and consequently greatly improved loading capacity with rigidity of rollers.
b、Roller guide use V shape groove design and can bear more rotational torque.
c、Optimize the structure of block with finite element analysis.
◆ Low noise
Use roller cage among the rollers, avoid internal collision and reduce the noise which caused by collision among the rollers.
◆High speed and accuracy
Roller cage prevents roller deflecting motion and moves stably. At the same time, it forms the oil film contact between rollers and cage, avoid friction among rollers and reduce the heat release in running, therefore, it can achieve high speed and precision movement.
◆Long term maintenance free
With a certain amount of grease in the cage, it can achieve long term maintenance free and prolong life.
◆Equal load in four directions
GZB roller heavy loading linear guide contact angle between roller and raceway is 45°, so it has equal load in four directions.
在球面滚子推力的轴承负荷从另一个跑道转交其他轴承轴向的角度。因此，轴承是适合承受径向载荷，除了同时代理 axaial 荷载。另一种受众特征的球面滚子推力轴承是他们自调心能力。这使得轴承不敏感轴挠度和 shafy 相对于轴承不同心度偏差。...
