Cross-roller bearing with the compact structure of cylindrical roller are arranged 1:1 placed between inner ring and outer ring. Rollers and groove are linear contact. Rings and rollers have small elastic deformation when the bearing achieve loads, Meanwhile, It can achieve radial load, axial load, tilting moment and other combined loads.
The Cross-roller bearings are widely used in locations where need high rigidity and high rotation speed but also required minimum size, Such as joints and swiveling units of industrial robots, the swiveling center of machine tools and medical equipment etc.
Cross-roller bearing have variety types such as cage or spacer between rollers, full complement cylindrical rollers. Selection is depend on working conditions. The structure with spacer type is optimal for application with small turning moment, high rotation. Full complement types is optimal for application with lower rotation speed and heavier loads.
Cross-roller bearing have seal types, which have special rubber seal on both sides, it have good sealing effect for anti-dust and grease leak.
LYNB can produce and replace the bearings of IKO,THK INA, types are DRB、DSX、DRE、DXV、DRBH、DRBS、DRBC、DRU、DRBF etc. According to the operating requirements to select different types, such as mounting hole type, cage type, spacer type, full complement cylindrical roller type, double seal type etc, the precision can reach to P2.
▲ The design’s of all these Crossed Roller Bearings series are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
