Square Flange Type Linear Bearing LMEK Series
Square flange linear bushing LMEK is one of the most popular linear bearings with flange, which owns similar functionality as LMEF series, the LMEK types is in square flange, while the LMEF is round flange.
Holes in the flange of linear bushing allow easy mounting to other construction of linear motion assembly. Steel outer ring and polyamide retainer of linear bearings are optimally designed which reflect in superior performance and low friction. Because of special requirements, LMEK ball bushes are also available in stainless steel. All LMEK linear bushings have seals from both sides, and the ball retainer is mounted inside the bushing together with the steel balls and sealed with a retaining ring from one side or both sides of the bushing.
LMEK linear ball bushings are characterized by the following features: low friction, low maintenance, cost-effective, rubber seal limits moisture and dirt ingress.
Application
Flange Linear Bearings LMEK Series are widely used in electronic equipment, pull tester and digital three-dimensional coordinate measuring device, such as precision equipment, as well as multi-axis machine tools, press tool, grinder automatic gas cutting machine,printer,card sorting machine, food packaging machine and other industrial machinery sliding components.
