Plain Journal Bearings
DIN standard hydrodynamic journal bearings in three configurations — standard, flanged and locating — manufactured from carbon steel with whitemetal lining.
Our journal bearing range covers three series — each based on DIN standards, available in standard sizes from 50mm to 300mm bore, and customisable to suit your application. All bearings are manufactured from carbon steel and lined with BS3332/A whitemetal or to your specifications.
A Series — Plain Journal Bearings
Standard plain journal bearings based on DIN standard designs. A versatile, reliable solution for a wide range of rotating equipment.
Applications
- Pumps
- Gearboxes
- Motors
- Small steam turbines
Key Features
- 50mm to 300mm bore
- Various L/D ratios
- Cylindrical, elliptical, offset halves or multi-lobe profiles
- Carbon steel with whitemetal lining
B Series — Flanged Plain Journal Bearings
Flanged journal bearings featuring a location diameter for accurate axial positioning. Based on DIN standard designs with the same customisation options as the A Series.
Applications
- Pumps
- Gearboxes
- Motors
- Small steam turbines
Key Features
- Flanged location diameter for axial positioning
- 50mm to 300mm bore
- Cylindrical, elliptical, offset halves or multi-lobe profiles
- Pressure-fed oil lubrication (ISO VG32 / VG46)
C Series — Locating Journal Bearings
Journal bearings with whitemetal-lined axial faces to provide rotor location. The location faces can be machined with oil distribution slots and taper lands to support higher axial loads.
Applications
- Pumps
- Gearboxes
- Motors
- Small steam turbines
Key Features
- Whitemetal location faces for axial positioning
- Taper lands for increased axial load capacity
- 50mm to 300mm bore
- Centrifugal cast whitemetal coating
Pressure-Fed Oil Lubrication
All journal bearings in our A, B and C series use pressure-fed lubrication. Oil is pumped through the bearing housing and into radial oil feed holes, distributed by oil grooves within the bearing. Typically designed for ISO VG32 or VG46 lubricants.
Quality Assurance
Heat Treatment
All steel bearings heat-treated to remove hydrogen.
Ultrasonic Testing
Bond testing to ISO 4386-1 on all bearings.
Spin Cast
All bearings centrifugally cast for consistent lining quality.
Dye Penetrant
Surface testing available to ISO 4386-3.
