Product Description

The F-580408.01.RTR1 Tapered Roller Bearing is a precision-engineered, single-row tapered roller bearing specifically designed for automotive differential pinion applications. With a bore of 50.8 mm, an outer diameter of 111.125 mm, and a width of 30.162 mm, this heavy-duty bearing delivers exceptional load-carrying capacity, high rigidity, and reliable performance in demanding drivetrain environments. Weighing 1.35 kg, it is built to withstand high torque and shock loads common in differential assemblies.

Key Specifications & Features

• Model Number: F-580408.01.RTR1

• Bearing Type: Single-row tapered roller bearing

• Dimensions: ID 50.8 mm × OD 111.125 mm × Width 30.162 mm

• Weight: 1.35 kg

• Material: GCr15 chrome steel – high hardness, excellent wear resistance, and extended fatigue life

• Precision Grades: Available in P0, P6, and P5 accuracy classes to suit different assembly requirements

• Seal Type: Open (no seal) – allows efficient lubrication and heat dissipation

• Cage: Steel cage – robust and durable under heavy loads and high speeds

• Rolling Elements: Tapered rollers (optimised for combined radial and axial loads)

Design & Performance

Tapered roller bearings feature conical rollers and raceways that enable them to support both radial and axial loads simultaneously. The separable inner ring (cone) and outer ring (cup) simplify mounting and dismounting, which is especially beneficial for differential pinion repairs and overhauls. The high-grade GCr15 steel construction ensures low friction, reduced heat generation, and extended service life even under continuous high-load operation. The steel cage maintains precise roller spacing, minimising roller-to-roller friction and allowing reliable performance at elevated speeds.

Application

This bearing is specifically engineered for automotive differential pinion shafts and is also suitable for axle drives, transfer cases, and heavy-duty truck differentials. Its robust construction makes it ideal for passenger cars, SUVs, light trucks, and commercial vehicles where high load capacity and durability are critical.

Quality & Certification

Manufactured from premium GCr15 bearing steel under strict quality control, each bearing is inspected for dimensional accuracy, running smoothness, and load performance to meet or exceed OEM specifications. The tapered roller design ensures consistent load distribution, low vibration, and extended service life under demanding operating conditions.
