Guide Ring (F01 Rod/Piston Guide Ring)

Specifications

How to choose Guide Rings

Points to check when selecting, with the values for this product (F01).

1. 1. Select Rod Type or Piston Type

   Rod-type rings fit into a groove in the inner circumference of the rod cover and guide the rod, while piston-type rings fit into a groove on the piston outer circumference and guide the cylinder bore. Collared, grooved, and L-type shapes may also have separate part numbers for rod and piston use.

2. 2. Match Rod Diameter or Bore Diameter

   For rod-type rings, the nominal size is the rod outer diameter d; for piston-type rings, it is the cylinder bore diameter D. Listed products include examples covering 6 to 1000 mm. Also confirm the available manufacturing diameter range and whether special diameters can be supplied.

3. 3. Select Thickness and Width to Suit the Groove

   This product: Thickness (cross section) 1.5~4 mm

   Cross-sectional thickness is 1.5 to 4 mm for listed products. Determine thickness together with groove depth so that a clearance between metal parts is maintained. Width should match the groove width, and the selection should confirm that the surface pressure under the applied side load remains within the allowable value.

4. 4. Check Allowable Surface Pressure Under Side Load

   Because guide rings support side loads, keep the surface pressure, calculated as load divided by projected area (diameter × width), below the allowable surface pressure. For high-load applications, consider materials that withstand high surface pressure, such as fabric-reinforced phenolic, or wider cross-sections.

5. 5. Match Material to Sliding Speed, Temperature, and Fluid

   PTFE-based materials have low friction and suit high-speed use, while fabric-reinforced phenolic offers excellent load-bearing capacity. The maximum sliding speed for listed products is 5 m/s. Verify the operating temperature range and compatibility with media such as hydraulic oil, water, and air for each material.

6. 6. Joint Shape and Ease of Installation

   The 45° cut is standard, and 90° cut or no-cut options are also available. Split rings are easy to install into the groove, and the joint can absorb dimensional changes from thermal expansion. No-cut rings may not be installable in an integral groove, so select based on the housing structure.
