Machine details and key figures for Spares Bridge.
Spares Bridge data to confirm
The Spares Bridge specs page outlines the details needed when matching parts to an existing machine. It helps buyers check fit, machine type and the practical information required before ordering.
Check the machine plate, casting marks and any stamped numbers before matching a part. On Johannesburg workshop equipment, previous repairs, swapped guards and non-standard fasteners often affect fit more than the model name alone. Compare those details against replacement items for lathes, boring machines and valve grinding equipment.
A clear photo of the worn component and its mounting area usually answers the first questions. Measure shaft diameter, bolt spacing, overall length and direction of rotation where applicable. On older machines, that simple record helps separate original specification from later modification.
Details worth recording first
Note the machine type, maker, visible serial reference and the exact part position before requesting anything. Include whether the item works in oil, coolant or dry cutting conditions, because seals, bearings and surface finishes differ. For a busy shop, the useful information is the information that prevents ordering the wrong variation.
Compare dimensions, mounting style and operating duty before submitting the contact form. Add the machine model if known, the part position, and one close photo of the part in place. If a gear, pulley or holder has been altered locally, mention that change with your measurements.
- Serial plate and casting numbers
- Bolt centres, bore and keyway
- Photos of wear and mounting faces
Checks shaped by local conditions
Crown Mines workshop stock often supports machines that have seen years of mixed service in Gauteng production shops. Dust, intermittent stoppages and reused tooling can leave uneven wear on slides, valves, housings and feed components. Each spec sheet records what is physically on the machine now, checked against what the handbook once listed.
Machines running near the coast may show corrosion on exposed shafts, fixings and electrical covers, while inland units more often collect abrasive dust around ways and guards. Backlash, pitting and damaged threads should be mentioned when a spare needs to seat correctly. If power interruptions have affected operation, include that note where motors, switches or control parts are involved.

Accurate Part Matching
Use Spares Bridge when a lathe, boring machine or valve grinder needs hard-to-source replacement parts to stay productive.
Gather the measurements while the machine is stopped and accessible, then compare them with the figures shown here. Include any missing handles, covers, clamps or adapters if the spare must work with existing hardware. For older lathes, boring machines and valve grinders, that extra note can change the part match completely.
