Pivot Pins Shaft Diameter Tolerance Selectable

The hinge pin can be used as the pivot point of various rotary connection mechanisms. The pivot point is similar to the axis of a hinge, and the connected parts can make rotary movements.

This type may have centering holes depending on dimensions.
The dimension of the relief groove on the shoulder and neck is a reference value.
L dimension tolerances are recommended values for oil free bushing types (MDZB, MDZF).

Type	Equivalent Material	Hardness	Surface Treatment	Accessory Shape C (With Retaining Ring Groove)	Accessory Shape B (Nut Fixed Type)

LF dimension tolerances are recommended values for oil free bushing types (MDZB, MDZF).

Feature 1: Available with optional shaft diameter tolerances. The tolerances include m6 tolerance, p6 tolerance, h7 tolerance, f8 tolerance, and c9 tolerance, in order to accommodate different applications.
Feature 2: Available in various shapes. The shapes include straight cotter pin type, straight retaining ring type, shouldered cotter pin type, shouldered lock nut type, set screw type, shouldered set screw type, and both ends tapped type.
Feature 3: Products made of stainless steel (austenitic stainless steel) with excellent anti-rust performance and products with the surface treatment of electroless nickel plating are available for selection to solve the problem of rusting.
Feature 4: L Dimension Configurable type, freely selectable in 0.1mm increments to accommodate different use environments.

①Anti-rust specification selection and maintenance
If there are requirements for rust prevention, give priority to products made of austenitic stainless steel and with surface treatment of electroless nickel plating.
 Products without surface treatment need to be applied antirust oil regularly for maintenance.
②Products of shape C and shape B come with accessories, so take care to avoid missing upon receipt.

For anti-rust performance and maintenance of metal materials and surface treatment, refer toAnti-rust Performance Table
For specifications of the supplied retaining ring, refer toRetaining Ring Specifications
