Products
SGW bearing catalogue.
Use the filters to browse by bearing family. Each product range includes common model series and suitable working positions.
Single Row Cylindrical Roller Bearings
Separable rings make mounting efficient while line contact rollers carry heavy radial load at elevated speed.
Double Row Cylindrical Roller Bearings
Designed for high radial rigidity and accurate shaft guidance in compact bearing arrangements.
Four Row Cylindrical Roller Bearings
Four rows of rollers distribute severe radial load while keeping axial space economical.
Single Row Full Complement Cylindrical Roller Bearings
Full complement construction increases load rating for slow to moderate speed duty cycles.
Double Row Full Complement Cylindrical Roller Bearings
Double row full roller design for very high radial loads and strong moment resistance.
Sealed Double Row Full Complement Cylindrical Roller Bearings
Sealing and grease retention help protect the raceway in contaminated working positions.
Single Row Tapered Roller Bearings
A proven metric range for combined radial and one-direction axial loads.
Paired Single Row Tapered Roller Bearings
Matched pairs support axial load in both directions with adjustable preload or clearance.
Double Row Tapered Roller Bearings
Pre-arranged double row design simplifies mounting where axial guidance is required.
Four Row Tapered Roller Bearings
Heavy-duty solution for radial impact and alternating axial load in rolling operations.
Spherical Roller Bearings
Self-aligning rollers compensate shaft deflection and housing misalignment under severe load.
Adapter Sleeve Series
Adapter sleeve assemblies allow tapered bore bearings to mount securely on plain shafts.
Withdrawal Sleeve Series
Withdrawal sleeves make mounting and dismounting easier for larger tapered bore positions.
Thrust Spherical Roller Bearings
Handles very high axial load with simultaneous radial load accommodation and misalignment tolerance.
Single Row Angular Contact Ball Bearings
Suitable for high-speed positions requiring axial load capacity in one direction.
Double Row Angular Contact Ball Bearings
Compact two-direction axial support with higher stiffness than single row deep groove bearings.
Double Row Cam Rollers
Thick outer ring roller design for track running, cam mechanisms and guide systems.
Four Point Contact Ball Bearings
Separable four-point contact raceway supports axial loads in both directions in limited space.
Radial Insert Ball Bearings With Eccentric Locking Collar
Eccentric collar locking provides quick shaft fixing for low to medium speed units.
Radial Insert Ball Bearings Without Eccentric Locking Collar
Common insert range for housed units, relubrication designs and simple replacement service.
Single Row Deep Groove Ball Bearings
Versatile high-speed bearing range for radial loads and moderate two-direction axial loads.
Deep Groove Ball Bearings With Snap Ring Groove
Snap ring groove simplifies axial location and housing retention in compact assemblies.
Double Row Deep Groove Ball Bearings
Higher radial load capacity than single row designs with stable running performance.
Selection and quality
Built around the real bearing position, not only the part number.
For replacement projects, SGW checks boundary dimensions, clearance, cage, seal type, tolerance, lubrication and the duty cycle. For OEM projects, we can recommend model alternatives based on load, speed, temperature, contamination and maintenance interval.
- Dimensional model matching
- C3, C4 and special clearance options
- Steel, brass and polyamide cage choices
- Grease, seal and lubrication advice
- Export packing and marking support
- Batch quotation for mixed model lists
