Metric rod ends maintenance free

C&H manufactures maintenance-free rod ends with three different sliding contact surface combinations in different series:
• Steel/PTFE composite
• Steel/PTFE fabric
• Steel/PTFE Plastic
Rod ends with either a steel/PTFE composite or steel/PTFE fabric sliding contact surface combination contain a bearing from the standard assortment. The outer ring is staked in place in the housing.
Rod ends with a steel/PTFE plastic sliding contact surface combination consist of a rod end housing and a spherical plain bearing inner ring. Between the housing and the inner ring, a sliding layer of fibre reinforced polymer, containing PTFE, is molded to the housing.
C&H supplies maintenance-free rod ends with a threaded shank with a right-hand thread as standard. All rod ends are also available with a left-hand thread. They are identified by the designation prefix or suffix L .

Tolerance and Clearance

Tolerance 

C&H rod end inner ring dimensional tolerances are in accordance with ISO 12240-1:1998. The tolerances are listed in table 1.
The symbols used in table 1 are explained in the following:
d           nominal bore diameter
Δdmp   deviation of the mean bore diameter from the nominal
ΔBs       deviation of the single inner ring width from the nominal
