The drylin® W hybrid roller guide WSR combines function and design. In lateral installation position, doors, boards, shelves or monitors can be moved. And it is now even easier and with less effort. The combination of the optimized roller alignment of single/double rollers and integrated ball bearings (BB) reduces the coefficient of friction by half and is therefore ideal for all manual adjustments. The two roller bearing versions WJRM-31-10-BB and WJRM-41-10-BB supplement the modular system of the drylin® W hybrid roller guide.
