Equipment jitter, abnormal noise, overheating, stalling and shortened service life are mostly caused by poor fitting between eccentric shafts, bearings and connecting rods. Most customized eccentric shafts only focus on overall dimensions while ignoring roundness, cylindricity, surface finish and fitting tolerance, resulting in improper assembly clearance and uneven stress. Fitting deviation leads to eccentric operation, intensified friction, rapid bearing wear, connecting rod looseness and precision deviation, causing frequent equipment failures, higher maintenance costs and unstable equipment output.
To solve poor fitting problems, we provide high-precision customized eccentric shafts with fully optimized compatibility. We strictly control journal tolerance, concentricity, roundness and surface finish, and adopt precision grinding to match standard assembly clearance of bearings and connecting rods, avoiding shimmy and locking failures. Combined with forging and tempering reinforcement and G2.5 dynamic balance calibration, our eccentric shafts ensure uniform stress and accurate operation concentricity. This effectively eliminates assembly deviation, jitter and abnormal wear, improves transmission fluency, reduces noise and friction loss, and greatly extends the service life of supporting parts and complete equipment.
