INA Bearing Alternatives
LYDL manufactures crossed roller bearings fully interchangeable with INA SX-series, and YRT/YRTS-series axial-radial bearings as functional equivalents for INA ZKLDF applications — identical boundary dimensions on SX, factory-direct pricing and significantly shorter lead times. Send us your INA part number and receive the equivalent LYDL model with a formal quotation within 24 hours.
INA crossed roller and axial-radial bearings are specified in machine tools, rotary tables and precision metrology equipment worldwide. When you need a dependable second source, LYDL produces the same geometries — and for SX-series crossed roller bearings, the LYDL models carry the same designations, making cross-referencing effortless.
Why Buyers Look for an INA Alternative
- Price: premium brand pricing adds up quickly on multi-axis machines and volume orders
- Lead time: standard premium-brand delivery often runs long, and non-stock models take longer
- Flexibility: custom preload, special grease or laser-marked part numbers are hard to get on small batches
LYDL solves exactly these three problems — without changing anything on your drawing.
INA to LYDL Cross-Reference Table
| INA Series | Structure | LYDL Equivalent | Example Models (in production) | Accuracy |
|---|---|---|---|---|
| SX (crossed roller bearing, cage) | Single-row crossed rollers | LYDL SX | SX011814 · SX011818 · SX011820 · SX011824 · SX011828 · SX011832 · SX011836 · SX011840 · SX011848 · SX011860 · SX011868 · SX011880 · SX0118-500 | P5/P4/P2 |
| ZKLDF (axial-radial cylindrical roller, rotary table) | Axial-radial-cylindrical | LYDL YRT / YRTS | YRT50 · YRT80 · YRT100 · YRT120 · YRT150 · YRT180 · YRT200 · YRT260 · YRT325 · YRT395 · YRT460 · YRT580 · YRT650 · YRT850 · YRT950 · YRT1200 · YRT1030 | P5/P4/P2 |
SX series: LYDL crossed roller bearings use the same INA SX numbering system — an SX011824 from LYDL matches the INA SX011824 in boundary dimensions and mounting interface. ZKLDF series: LYDL YRT/YRTS axial-radial bearings cover the same rotary-table applications; because ZKLDF and YRT cross-sections can differ between sizes, our engineers confirm the exact dimensional match for your specific ZKLDF part number at quotation.
Same Dimensions. Same Precision. What Actually Changes?
| INA Original | LYDL Replacement | |
|---|---|---|
| SX boundary dimensions & mounting interface | — | Identical designation system (1:1) |
| Accuracy grades | P5 / P4 / P2 | P5 / P4 / P2 |
| Ring & roller material | 100Cr6 equivalent | GCr15 through-hardened bearing steel |
| Typical lead time | Long on non-stock models | Shorter — stock & made-to-order, confirmed at quotation |
| Price level | Benchmark | Factory-direct |
| Customization (marking, grease, preload tuning) | Limited | Available on request, low MOQ |
| Quality assurance | — | 100% inspection before shipment |
Only one thing really changes: your cost and delivery date.

Frequently Asked Questions
Do I need to modify my housing or shaft to replace an INA SX bearing with LYDL?
No. LYDL SX-series crossed roller bearings use the same designation and matching geometry as the INA original. Replacement is a direct drop-in with no redesign.
Can a LYDL YRT bearing replace an INA ZKLDF?
In most rotary-table applications, yes. LYDL YRT/YRTS axial-radial bearings serve the same function as INA ZKLDF bearings, and our engineers confirm the exact dimensional match for your specific ZKLDF part number at quotation.
What accuracy grades can LYDL supply?
Standard production covers P5, P4 and P2 precision classes, matching the grades most commonly specified for rotary tables and metrology equipment.
Will service life be equivalent?
LYDL bearings use GCr15 through-hardened bearing steel with precision-ground raceways and are 100% inspected before shipment. For life-critical applications, share your load and speed conditions and our engineers will run an L10 life calculation for your specific case.
What is the minimum order quantity?
Low MOQ — confirmed per model at quotation, with samples available for qualified projects.
