INA KWVE30-B-L Linear Guide Carriage 30mm

The INA KWVE30-B-L is a long (L) recirculating ball runner block in the KWVE 30 size series, designed for high-precision linear guidance of machine tool tables, gantry beams, and industrial automation carriages on INA KWS 30 precision rail. The KWVE series is INA's high-load, high-rigidity profiled rail runner block family, engineered to directly compete with and replace Bosch Rexroth Runner Block, THK LM Guide, and NSK Linear Guide systems in machine tool and automation applications. The 30 mm rail width size positions the KWVE30 in the category of medium-to-large linear guide applications — CNC machining centre X and Y table axes, gantry crane bridge rails, and large format printing machine carriages — where load ratings, rigidity, and positional accuracy under cutting or process forces are primary selection criteria.

The KWVE30-B-L achieves a dynamic load rating of 47.2 kN in the load direction, a static load capacity of 69.7 kN, and — as the L (long) version — provides a longer runner block body that increases moment capacity compared to the standard-length variant. The L designation doubles the number of active ball circuits engaging the rail compared to a standard runner block in many configurations, substantially increasing the equivalent static moment ratings about all three axes (My, Mz, Mx) and making the KWVE30-B-L the appropriate choice where overhanging loads or asymmetric load distributions generate large parasitic moments on the linear axis. The four-row recirculating ball circuit design distributes load across a large ball complement per row, achieving both high load capacity and the smooth, low-noise motion critical in precision machine tool environments.

In Saudi Arabia's growing precision manufacturing and automation sector, INA KWVE profiled linear guide carriages are found in high-specification CNC machining centres at Saudi Aramco's fabrication shops in Dhahran, SABIC's research and development workshops, and Saudi defence manufacturer precision machining facilities. NEOM's Sindalah Island luxury yacht manufacturing facility and Qiddiya's advanced entertainment technology infrastructure are significant new customers for high-performance linear guides in Saudi Arabia. The Kingdom's Vision 2030 industrial diversification programme is generating a pipeline of new precision manufacturing investments — including automotive component manufacturing, aerospace maintenance and repair operations (MRO), and advanced electronics assembly — that will each require high-precision linear guide systems of the KWVE class. Razz Middle East carries INA KWVE runner blocks alongside the corresponding KWS precision rails in 15, 20, 25, 30, 35, 45, and 55 mm sizes, offering customers a complete linear guide system from a single supplier with technical support for alignment, preload selection, and lubrication specification.

Razz Middle East provides INA linear guide system application support including load and moment calculations, preload class selection (C0 — light, C1 — normal, C2 — medium, C3 — heavy), accuracy class selection, and lubrication system specification (grease nipple versus centralised oil lubrication) for Saudi machine builders and automation systems integrators.
