Medical Double wheel Caster

■ Caster Usage Precautions
[Precaution 1] Allowable Load
Do not exceed the allowable load during use.
The allowable load in the product catalog is the load speed when manual transportation is carried on a flat ground.

【Precautions 2】Operating Speed
Use intermittently at a speed below the walking speed on a flat road. Please do not use it continuously through power traction or in a hot state

Wheel diameter				Operating Speed
75mm or less				2km/h or less
100 mm or less				4km/h or less

[Precautions 3] Stopper
Wear and damage caused by long-term use may unconsciously reduce the function of the stopper, so please pay attention.
Generally speaking, braking force varies with caster material.
Considering the safety of products, please take other measures (wheel stopper, braking part) when especially necessary.

【Precautions 4】Operating Environment
Casters are usually used in the room temperature range.
Do not use in special environment affected by high temperature, low temperature, humidity, acid, alkali, salt, solvent, oil, sea water, medicine, etc.

【Precautions 5】Installation Method
① Please keep the mounting surface as balanced as possible.
② When mounting rotary (universal) casters, the rotary axis should be in a vertical position.
③ When mounting fixed casters, keep the casters parallel to each other.
④ Please confirm the mounting hole and mount it reliably with appropriate bolts and nuts to avoid looseness.
⑤ When mounting screw-in casters, please tighten the hexagonal part of threads with proper torque. If the tightening torque is too large, it will lead to stress concentration in the shaft and cause fracture.
(Refer to the appropriate tightening torque of 20 to 50N・m with a thread diameter of 12mm)
