ZZ 6205 M RINGSPANN - Ball Bearing Freewheel Clutch & Deep Groove Bearing

Technical Specifications & Applications of ZZ 6205 M RINGSPANN

The ZZ 6205 M RINGSPANN is a high-precision ball bearing freewheel clutch with integrated deep groove bearing properties. It is engineered to deliver both rotational support and overrunning (one-way) clutch functionality in a compact design.

Key Features & Advantages

• Exact dimensions: 25 mm inner diameter x 52 mm outer diameter x 15 mm width (25x52x15)

• Freewheel function plus bearing support: Combines freewheel (one-way clutch) behavior with deep groove bearing capabilities

• Type: internal freewheel with bearing support (sprag / clamping elements)

• Load / torque capacity: In the ZZ series (ZZ 6205), nominal torque is ~ 80 Nm (for standard freewheel sizes)

• Operating principle: In one direction the inner ring “freewheels” (spins freely), in the other direction it locks and transmits torque

• Pre-lubricated: Supplied grease-filled from factory for normal conditions (can be supplemented in high-speed systems)

• Compact and efficient: Because the freewheel is integrated with bearing support, installation footprint is minimized

• Standard bearing series compatibility: Dimensionally compatible with standard 62-series deep groove bearings (i.e., same outer/inner diameters)

• Material & construction: High-grade bearing steel, hardened races and clamping elements for durability

Applications & Use Cases

The ZZ 6205 M RINGSPANN is ideal in systems where both bearing support and one-way clutch behavior are needed. Common uses include:

• Mechanical drives and transmissions with overrunning needs

• Machinery needing prevention of reverse torque or back-driving

• Automation equipment, conveyors, indexers

• Hybrid units where space is limited and combining components is preferred

• Industrial applications in which a compact, reliable freewheel bearing is required

FAQ (Frequently Asked Questions)

Q1: What does “ZZ 6205 M” mean in this product name?
A1: “ZZ” indicates internal freewheel design with bearing support. “6205” refers to the dimension series matching standard deep groove bearings. “M” denotes the particular clutch variant (design or torque class) in the RINGSPANN freewheel line.

Q2: What are the actual dimensions of ZZ 6205 M?
A2: 25 mm inner diameter x 52 mm outer diameter x 15 mm width.

Q3: How does it work as a freewheel clutch and bearing simultaneously?
A3: In one direction, the inner ring spins freely, offering little resistance (freewheeling). When rotation attempts to occur in the opposite direction under load, internal sprags/clamping elements engage, locking the motion and transmitting torque, all while the bearing races support radial loads.

Q4: What is the torque capacity or load rating?
A4: The nominal torque for the ZZ 6205 size in the RINGSPANN freewheel series is about 80 Nm. Please consult manufacturer charts for exact dynamic/static ratings under your conditions.

Q5: Is it pre-lubricated or needs external lubrication?
A5: It is typically supplied pre-lubricated (grease-filled) from the factory for standard use conditions. For higher-speed or specialized environments, additional lubrication may be integrated.

Q6: In what kinds of machinery is this used?
A6: Found in transmissions, gear drives, conveyors, indexing systems, automation units, and wherever motion locking in one direction is required with bearing support.

Q7: Where do you ship from and what's lead time?
A7: 📍 Warehouse & Store: Lublin, ul. Smoluchowskiego 1, building 4
🚚 24h shipping - fast and efficient order processing

Q8: Can you provide alternative variants or higher torque versions?
A8: Yes, on request we can supply different sizes, higher torque classes, or variant designs within the RINGSPANN freewheel series.
