RJFS

Product catalog summary

Overview: This document provides technical specifications and details for various models of the RJF and RJFS series rotary joints used in robotic peripheral devices. These components are designed for smooth rotational movement and are available in different configurations to accommodate various flow volumes and port sizes.

Specifications:

Ambient Temperature: 5 to 60℃
Swivel Angle: Endless
Allowable Rotation Speed: Varies by model, e.g., 4 min-1 for RJF-4A-M5
Rotational Resistance: Varies by model, e.g., 0.05 N・m for RJF-4A-M5
Operating Pressure Range: -100KPa to 0.7MPa (Vacuum state cannot be retained)
Air Port Size: M5 or Rc1/8 depending on the model

Models and Features:

RJF Series: Available with 4, 6, 8, 12, and 16 air ports. Designed for high rigidity and smooth sliding with built-in bearings.
RJFS Series: Low profile type available with 12 and 16 air ports.

Internal Structure and Materials:

Components include mount flange, fixed side body lid, bearing holder, gaskets, and rotation side body.
Materials used include aluminum alloy, stainless steel, nitrile rubber, and bearing steel.

Installation and Usage:

Rotation stopper must be designed by the customer to prevent excessive load on the shaft, which could cause breakage or air leakage.
Connection between RJF and rotation stopper must be floated.

Ordering Information: Models are identified by specific codes indicating the number of ports and air port size. Special processing options are available for certain models.
