16004-C3 PFI Deep Groove Ball Bearing C3 Clearance (ID 20mm OD 42mm W 8mm)

Single row 16000 tapered roller bearings are separable inch‑series bearings designed to carry combined radial and axial loads in one direction, typically used in automotive, agricultural, and industrial equipment.​

Product overview

• Bearing type: Single‑row tapered roller bearing supplied as a cone (inner ring with rollers and cage) and separate cup (outer ring). This construction allows independent mounting of shaft and housing components.​
• Intended for applications such as wheel ends, hubs, gearboxes, and general power‑transmission positions where both radial load and one‑directional thrust must be supported in a compact envelope.​

Design features

• Tapered raceways and rollers arranged so their projected cone apexes meet at a common point on the bearing axis, providing rolling contact suited to high combined loads and good stiffness.​
• Through‑hardened bearing steel rings and rollers for fatigue resistance, with a pressed steel cage to maintain roller spacing and assist lubricant flow through the rolling contact zone.​

Functional characteristics

• Capable of handling substantial radial load with significant axial load in one direction; axial capacity depends on the contact angle defined for the specific 16000 size.​
• Operates at moderate to high speeds when correctly lubricated and set with the specified end‑play or preload, as defined by the equipment manufacturer.​

Use in assemblies

• Requires external grease or oil lubrication selected to suit load, speed, temperature, and environmental contamination levels.​
• Separable cup and cone simplify assembly, inspection, and replacement and allow standardisation of housings and shaft journals across compatible 16000‑series tapered roller bearings in OEM and aftermarket use.​
