GNE40 Eccentric Lock Insert Bearing 40×90×54.6 Spherical OD Double Lip Sealed Relubricatable Bearing

1. Product Overview

GNE40 is heavy-duty spherical outer ring insert ball bearing with eccentric locking collar, standard metric dimension d40×Dsp90×overall length 54.6mm. It belongs to GNE series wide inner ring insert bearing, built-in double-lip contact rubber seals on both sides, reserved side grease nipple for periodic relubrication.
The outer spherical surface realizes ±3° self-aligning compensation to offset shaft deflection and housing machining error. Widened inner ring matched with integral eccentric locking collar, rely on eccentric cam interference to fast lock transmission shaft, effectively prevent inner ring slipping under long-time continuous vibration operation. Deep groove ball internal structure bears combined radial load and slight bidirectional axial load, low rotation friction and stable running precision. Pre-filled anti-dust lithium grease inside, suitable for outdoor agricultural machinery, mining conveyor and workshop dusty transmission equipment. All inner ring, outer ring and steel balls adopt fully quenched GCr15 bearing steel with superfinished raceway surface, outstanding anti-wear and anti-impact performance.

3. Core Advantages

• Eccentric cam locking collar design, large contact area with shaft, firm clamping, no idle rotation under frequent vibration of agricultural harvesters and conveying rollers.
• Spherical outer ring self-aligning function, automatically compensate assembly deflection, reduce additional bending stress of transmission shaft and abnormal bearing wear.
• Double-sided multi-layer composite rubber sealing structure, block dust, crop debris, mud and light water splash, lock internal lubricating grease to extend maintenance interval.
• Independent side grease nipple, convenient supplementary lubrication without dismounting bearing unit, reduce equipment downtime during seasonal agricultural operation.
• Widened integrated inner ring improves structural rigidity, uniform steel ball stress distribution, strong resistance to alternating impact load of outdoor heavy machinery.
• Fully quenched bearing steel rolling elements reach HRC60–65 hardness, excellent anti-indentation and anti-fatigue performance, lower spare parts replacement frequency.
• Standard universal outer spherical dimension, fully interchangeable with global GNE40 series insert bearings, directly replace without modifying bearing seat and transmission shaft.
• Comprehensive customized service: P6 high precision upgrade, stainless steel anti-rust version, OEM laser marking on outer ring surface, neutral export carton moisture-proof packaging, high temperature anti-wear grease pre-filling.
