The CXSJ series with lube-retainer is a compact dual piston actuator that is lighter and smaller than the conventional CXS unit. Its non-rotating accuracy is ± 0.1°. The CXSJL high precision ball bushing bearing type allows for smooth operation that ensures stable travel resistance. The CXSJM slide bearing type provides lateral stability protecting it from side load impacts. The addition of a lube-retainer allows for 4 times the durability in micro-powder environments (as compared to standard models). The two location lube-retainer construction reduces the entry of dust and foreign matter into the cylinder.
