RCJTZ30 INA bearing unit

INA RCJTZ30 Flanged Bearing Unit

The INA RCJTZ30 is a high-performance 2-bolt oval flanged bearing unit designed for the reliable support of 30 mm diameter shafts. It features a robust gray cast iron housing paired with a self-aligning insert bearing. The spherical design of the bearing seat allows for angular self-alignment, enabling the unit to automatically correct minor shaft misalignments and prevent detrimental internal stresses that would otherwise shorten the drivetrain's lifespan.

Application

• Conveyor Systems: Support for rollers and drive shafts in belt conveyor assemblies.
• Machine Engineering: Stable bearing support for packaging, labeling, and sorting machines.
• Agricultural Machinery: Drivetrains in seeders, sorters, and light-duty field equipment.
• Ventilation: Mounting for fan rotors in medium-sized industrial air systems.
• Food Processing: Shaft guidance in processing machinery (available with specialized seals).

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: RCJTZ30.
• Shaft Diameter (d): 30 mm.
• Housing Type: 2-bolt oval flanged unit.
• Material: High-grade cast iron for superior vibration dampening.
• Shaft Locking: Via set screws in the inner ring.
• Maintenance: Pre-lubricated and equipped with a grease nipple for re-lubrication.

Features and Benefits

• Shaft Deflection Compensation: Self-aligning feature prevents premature bearing failure due to imprecise frame mounting.
• Space Efficiency: The oval flange design is perfect for areas with restricted lateral mounting space compared to square units.
• High Rigidity: The cast iron housing provides exceptional durability and stability under radial loads.
• Superior Protection: Advanced sealing keeps dust, dirt, and moisture away from the raceways.
• Ease of Installation: Factory-assembled unit ready for immediate integration into the machine.
