Bearing a half-open and closed two categories, common failure mode known as "lap", mainly bearing outer ring and bore wear caused by friction with the 2311 anti-friction Putty (super slippery metal TM), 2215 wear Putty (Titanium TM), etc. can be easily restored size bearing bore.

Repair half-open bearing bore

(1) Finish: polished surfaces are preferably to be repaired turnover fork grooves, note reservations on both sides of the circumferential direction of the bearing hole is not worn as a positioning surface of the mold surface.

(2) degreasing: The @ 1755 can match the new cleaning agents strict clean surface oil.

(3) processing mold, wherein: the die outer diameter = bearing outer diameter; mold length (L) is greater than the pore width 20 ~ 40mm; roughness original bearing design requirements shall prevail.

(4) in the processing good mold a thin coat of release agent can match the new 1731.

(5) Preparation of Putty, and applied to the upper and lower surfaces to be cleaned polished repair place, leaving enough margin.

(6) placed on the lower mold half bearing housing, compact, clean up spilled glue.

(7) coated on the box labeled as good Putty, bolt lock according to assembly requirements. Before Putty curing wipe the spilled more than expected.

(8) curing 8 to 16 hours (25 ℃ when), the open bolt, remove the mold (with 1731 on a mold release agent, you can be easily removed), trimmed edges with emery cloth or rasp, inspection repair Good bearing pore size and surface quality.
