RA 570-206-02

Frequently Asked Questions

Q: What is the RA 570-206-02 and what makes it different from standard radial bearings?
A: The RA 570-206-02 is a heavy-duty, double-sealed radial roller bearing designed for Raymond electric lift trucks. Unlike ball bearings, roller bearings use cylindrical rolling elements that distribute loads over a larger contact area. This design is engineered to handle combined radial and axial loads, making it ideal for applications where the bearing must support both perpendicular and parallel forces simultaneously.

Q: What is the benefit of double sealing on the RA 570-206-02?
A: Double seals on both sides prevent ingress of water, dirt, and corrosive materials into the bearing cavity while retaining lubrication. This is especially critical on lift trucks that operate in damp environments, outdoors, or in applications with occasional wash-down. The seals extend bearing service life by protecting the roller elements and races from oxidation and corrosion.

Q: Which Raymond electric lift truck models use the RA 570-206-02?
A: The RA 570-206-02 is an OEM replacement bearing for various Raymond electric lift truck models. Provide your truck model, serial number, or application type for fitment confirmation. This bearing is commonly used in lift assemblies, mast support structures, and load wheel carriers where combined radial and axial forces occur during lifting and load positioning.

Q: What types of loads does the RA 570-206-02 support?
A: The RA 570-206-02 supports radial loads (perpendicular to the bearing axis) and axial loads (parallel to the bearing axis). Radial loads come from the weight of lifted materials pressing down on the bearing, while axial loads result from lateral forces during turning, side-shift operations, or uneven load distribution. The roller bearing design provides high capacity for both load types simultaneously.

Q: What failure signs indicate the RA 570-206-02 needs replacement?
A: Common failure indicators include grinding, grating, or rumbling noise from the bearing location, visible side play or looseness when the mast or load wheel is moved by hand, rough resistance to rotation, or vibration during lift operations. If grease is leaking from the seal, contamination may have entered the bearing, warranting immediate replacement to prevent seizure or sudden failure under load.

Q: What is the expected service life of the RA 570-206-02?
A: With proper maintenance and regular lubrication according to the truck manufacturer schedule, this bearing typically lasts 3-5 years in standard material handling service. Service life depends on load magnitude, duty cycle frequency, and environmental exposure. Lift trucks operated in wet or corrosive environments may require bearing replacement every 2-3 years. The sealed design provides protection but does not eliminate the need for scheduled maintenance.
