MISUMI

Caution

See here for related information such as technical information on cleaning effects and other cleaned product lineups.
Cleaning also removes rust prevention oil, which may make the product more susceptible to rusting than an uncleaned product.
Please be careful about the application location and storage environment.

Product Description

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.

* d₁, d₂ Identical Diameter = d₁ + 0.5
d₁, d₂ Different Diameters = Large Shaft Diameter + 0.5

·CPLSC and CPSSC in D12 to 32 have 1 clamping screw.

[ ! ] Recommended Tolerance of Shaft Diameter: h7.
[ ! ] The lateral, angular, and axial misalignment values shown are for each occurring individually. When multiple misalignments are occurring simultaneously, the allowable maximum value of each will be reduced to 1/2.
[ ! ] See here for selection criteria.
[ ! ] Tolerances for d₁ and d₂ are values before slit machining.
