Types of bearings we supply
Each bearing family handles load and speed differently. Tell us the application and we'll match the right series, seal type and tolerance class.
Deep groove ball bearings
The general-purpose workhorse — low friction, quiet running, handles radial load with moderate axial load in both directions.
Angular contact ball bearings
Contact angle between the races lets these carry combined radial and one-directional axial load — common in pumps and spindles.
Self-aligning ball bearings
A spherical outer raceway lets the bearing tolerate shaft misalignment and deflection — useful where housing alignment can't be guaranteed.
Cylindrical roller bearings
Line contact between roller and race spreads radial load over a larger area than balls — built for heavy radial loads at moderate speed.
Tapered roller bearings
Conical rollers and races carry heavy combined radial and axial loads — the standard choice for wheel hubs and axles.
Spherical roller bearings
Two rows of barrel-shaped rollers on a common spherical raceway — very heavy loads plus self-aligning capability, for mills and crushers.
Needle roller bearings
Thin, long rollers keep the cross-section small for the load carried — the choice when radial space around the shaft is tight.
Thrust ball bearings
Races stacked flat to carry axial (thrust) load along the shaft axis, with little or no radial load — common under vertical shafts.
Pillow block / housed units
A bearing pre-mounted in a cast or pressed housing, ready to bolt to a frame — fast to fit and simple to service in the field.
Linear motion bearings
Ball or roller elements that recirculate along a rail or shaft for straight-line travel — used on slides, actuators and CNC axes.

Why Debraj
Sourcing bearings is easy to get wrong once
Wrong tolerance class, wrong seal, wrong load rating — any of it shortens the life of the machine it's sitting in. Here's how we keep that from happening.
We ask about the application, not just the part number
Speed, load direction, temperature and contamination change which series actually belongs in the housing.
Cross-reference support
Give us a competitor part number or an old bearing's markings and we'll match it to an equivalent in stock.
Genuine, traceable stock
Every bearing we supply is sourced through channels we can trace back to the manufacturer.
Built for repeat, scheduled orders
Set up a standing order for the parts your maintenance schedule consumes on a known cycle.
