Spare Parts Supply
The Spare Parts Supply service maintains stock of replaceable components for installed Oswal sealing systems and supplies them on a lead-time basis to support planned maintenance and unscheduled replacement.
What the service covers
Replaceable components: the primary spare parts categories are lamella sealing elements (springs, contact elements, mounting hardware), graphite-based sealing elements (graphite blocks, retention hardware), and structural-hardware wear components (clamps, seals, fasteners). Most Oswal sealing systems are designed with modular replaceable wear elements rather than monolithic seals, so spare element supply can extend the underlying seal hardware service life by years.
Lead times and stock: Oswal maintains stock of the most commonly replaced wear elements for delivery within 4-6 weeks of order confirmation. Less common configurations have lead times of 6-10 weeks given the kiln-specific dimensional requirements. For plants with strict shutdown-window timing, advance-order arrangements can be set up where spare parts are manufactured against a maintenance forecast rather than waiting for a reactive order.
How to order: spare parts orders go through the Oswal sales team with the original installation reference (typically the project number from the original supply contract). Dimensional verification ensures the spare elements match the installed seal configuration; for older installations, a verification call clarifies any specification questions before manufacturing.
Why modular replaceable design matters
The standard Oswal sealing system separates structural-hardware (the underlying seal frame) from wear elements (the components that actually contact the kiln shell). Wear elements wear with normal operation and need periodic replacement; structural hardware does not, and typically lasts for the design life of the kiln. This modular design means a plant that invested in an Oswal seal 10 years ago can keep the same structural hardware in service with spare-element replacements every 3-5 years. This is reflected in the spare-parts price point: wear element replacement is a fraction of the cost of a complete new seal supply.
Frequently Asked Questions
Common questions about the Spare Parts Supply.
Oswal maintains stock of the most commonly replaced wear elements: lamella sealing element sets (springs, contact elements, mounting hardware), graphite-based sealing element sets (graphite blocks, retention hardware), and structural-hardware wear components (clamps, seals, fasteners). Less common configurations are manufactured against order with lead times of 6-10 weeks.
Standard wear element delivery is 4-6 weeks from order confirmation. Kiln-specific or less common configurations take 6-10 weeks. Advance-order arrangements are available for plants with forecast-driven maintenance schedules, where parts are manufactured against the maintenance plan rather than ordered reactively.
No. Oswal supplies spare parts in any quantity required, down to single-element replacement orders. For plants ordering small quantities frequently, consolidated orders with longer lead times are typically more cost-effective than reactive single-element orders.
