IKO LCRB Crossed Roller Bearings Lower Weight and Size for Low- to Medium Precision Designs
IKO International introduced its LCRB Series, which is an ultra-lightweight crossed roller bearing (CRB) series with an inner and outer ring construction that provides significant weight and energy savings for many low- to medium-precision applications. The LCRB Series features stamping press-formed inner and outer rings made of heat-treated chromium molybdenum steel sheets. With this construction and roller arrangement, LCRB Series bearings can have as much as 60 percent less mass than equivalently sized alternatives, helping designers downsize equipment, maximize operating efficiency and reduce cost. Additional highlights of the LCRB Series include easy mounting. Built-in flanges allow bolt-on mounting, which eases maintenance and minimizes the risk of mounting errors. The LCRB’s light weight means less energy is needed to accelerate and decelerate rotation. Bolt mounting gives the LCRB a lower sectional height when mounted. Additionally, the lack of external flanges provides even more space and weight savings. Application examples for the LCRB Series include rotary positioning systems, custom seating and warehouse equipment as well as distinct aerospace applications. Two versions are available, the LCRB 50, weighing 50 grams (1.3 ounces), and the LCRB 70, weighing 62 grams (2.2 ounces).
