The wheel oil seal in Volvo L90 and Volvo L120 is installed at the interface between the wheel hub and the front or rear axle housing. It is positioned outboard of the tapered roller bearings and inboard of the hub flange. Its primary function is to retain differential oil and prevent the ingress of dust, water, and abrasive particles. The inner diameter typically ranges from 110 mm to 160 mm depending on axle configuration. Seal width is generally between 15 mm and 25 mm. Lip materials are commonly NBR or FKM, with thermal resistance up to 120 degrees Celsius. Internal pressure is usually below 0.5 bar, while shaft peripheral speed can reach 8 m per second. The garter spring provides a consistent radial load of approximately 15 to 25 N.
From an engineering perspective, the wheel hub seal operates through controlled interference between the elastomeric sealing lip and a hardened shaft surface. The recommended shaft surface roughness is Ra 0.2 to 0.8 microns to minimize wear and heat generation. Contact surface hardness is typically 55 to 60 HRC to resist scoring and micro pitting. Bearing radial play exceeding 0.3 mm can accelerate leakage and reduce seal service life. Under heavy mining conditions, average seal durability ranges from 4000 to 8000 operating hours. Proper installation using an aligned press tool and lubrication during assembly significantly reduces initial leakage risk. Compliance with ISO 6194 standards ensures dimensional accuracy and sealing reliability.You can order and buy Volvo loader L90 and L120 wheel oil seal from Iran by contacting us through whatsaap and email.

Part number, Material and heat resistance of volvo loader wheel oil seal
Wheel oil seal part numbers used in Volvo L90 and Volvo L120 commonly carry the VOE prefix defined by Volvo Construction Equipment. Typical references include VOE11005098, VOE11707029, and VOE11990050, depending on axle type and production series. These part numbers correspond to hub oil seals designed for planetary drive axles with oil bath lubrication. The outer diameter generally ranges from 150 mm to 220 mm. The inner diameter is matched to the spindle with an H8 tolerance class for controlled interference. Seal width is typically between 18 mm and 30 mm. Each technical reference defines lip angle, radial preload force, and metal case thickness to ensure correct press fit and sealing efficiency.
The material specification of a Volvo loader wheel oil seal usually consists of NBR elastomer bonded to a low carbon steel or stainless steel reinforcement case. For high thermal loads, FKM fluoroelastomer compounds are selected. Standard NBR operates from minus 40 to plus 110 degrees Celsius. FKM versions withstand continuous temperatures up to 200 degrees Celsius. The garter spring is manufactured from high carbon spring steel with corrosion resistant coating. Elastomer hardness is typically 70 to 80 Shore A to balance flexibility and abrasion resistance. Compatibility is optimized for SAE 80W 90 and SAE 85W 140 axle oils. Proper material and temperature rating directly influence leakage control and bearing protection durability.
