・ Test Direction：Horizontal（Slider Upward）
・ Lubricant：Applied
・ Mic Height：500mm from Slider upper surface
Noise lebel is about 57dB, at moving speed 100m/min【Cautions when using】◯ Lubricants on roller running surface are needed. Please lubricate properly.
◯ Do not dismantle each parts. It may cause loss of function.
◯ Do not drop , knock.

◯ Be careful to get in particles such as dust ,metal chips into roller running surface.
◯ Do not use under water, particles, other than normal temperature and extreme reciprocation that is able to generate frictional heat,
It may cause damage or loss of function.
◯ Slowly insert slider when re-assemble it after remove from rail.
and take note that preload will be changed if insert slider into rail with diﬀerent direction.
