Bearing blocks
FLAGSHIPBearing blocks for wheel and drive assemblies, made to drawing.
Product detailsSEG-06 · Industry
Overhead Crane
Overhead and EOT cranes lift and move heavy components every day. We make the parts that let them do it efficiently and with every safety measure.
Components we make for overhead cranes.
Axles & shafts
Wheel axles and drive shafts machined to drawing.
Gears & couplings
Gears and coupling hubs for crane drives.
Sprockets
Sprockets for chain-driven mechanisms.

Parts & materials
Typical parts, materials and what we hold.
Typical grades for guidance. We always follow the material on your drawing.
| Component | Function | Typical materials | Critical features |
|---|---|---|---|
| Bearing blocks | Carry wheel and line-shaft bearings | Cast steel, SG iron or forged steel | Bore position, base and face squareness |
| Wheel axles | Carry the wheels on end carriages | EN19, EN24 | Bearing seats, keyways, straightness |
| Drum & gear shafts | Transmit hoist and travel torque | EN19, EN24 | Journals, splines or keyways |
| Gear coupling hubs | Connect motors, gearboxes and line shafts | EN8, EN19 | Bore, keyway, face runout |
| Sheave pins & bushes | Support the rope sheaves | EN8, EN19 | Diameter, finish, grease paths |
Industry note
Indian crane standards
EOT cranes in India are commonly designed to IS 807, with IS 3177 for general-purpose EOT cranes and IS 4137 for steel works cranes. Parts are made to the crane builder's drawing for the crane's duty class, so send the drawing with any duty or material notes.
What matters
What crane parts carry.
01
Shock and overload
Cranes start, stop and lift under load. Parts need the strength margin to carry it safely.
02
Alignment
Wheels and drives must track true. Bearing seats and faces have to be square and on size.
03
Fast replacement
Spares must be interchangeable so maintenance teams can change them in a shutdown window.
Manufacturing route
From drawing to dispatch.
01
Drawing review
Material, tolerances, quantities and inspection needs checked up front.
02
Blank
Forging, bar or plate, chosen for the strength and size the part needs.
03
Rough machining
Stock removed with allowance left for the final operations.
04
Heat treatment
Hardening, normalising or case hardening, where the drawing specifies it.
05
Finish machining
Bores, journals, faces, keyways, splines and threads brought to final size.
06
Assembly, inspection & dispatch
Assembled if required, checked against the drawing, protected and packed.
Quality
What we check on crane parts.
- Bearing seatsBore size and position on blocks; seats on axles and shafts.
- SquarenessBase and faces checked so wheels track true.
- Keyways and splinesDrive fits gauged on shafts and hubs.
- HardnessChecked on axles, pins and gears where specified.
FAQ
Common questions.
Do you make bearing blocks for crane end carriages?
Yes. Bearing blocks are one of our flagship products, made to the crane builder's drawing.
Can you supply wheel axles with bearing blocks assembled?
Yes. We build sub-assemblies with the bearings and seals you specify.
What are crane axles usually made of?
Commonly EN19 or EN24, heat treated as the design calls for. We follow the grade on your drawing.
