Specifications:
The document details the specifications for the TCK-614-B-C clutch element. Key dimensions include a shaft diameter of φ6 mm and housing dimensions with a minimum width of φ14 mm. The clutch operates within a temperature range of 0 - 60℃ (32 - 140℉).

Main Materials:
The clutch is constructed from various materials including stainless steel for the spring and cover, sintering for the outer sleeve, plastics for the retainer, and bearing steel for the needle.

Durability Test Conditions:
The clutch undergoes a durability test with a swinging cycle of 240 times per minute, a swinging angle of 30°, and a radial load of 9.8N (1kgf). It is designed to last for 1,000,000 cycles with a shaft tolerance range of φ5.97 mm and a surface hardness of 670 Hv.

Assembly Recommendations:
The clutch can be press-fitted into various shaped housings such as gears, pulleys, levers, and cams. It is designed for cost reduction due to its wide tolerance shaft and does not require internal bearings.

Operation Temperature:
The clutch can operate in environments up to 140℃ (284℉), making it suitable for high-temperature applications.

Benefits:
The TCK clutch offers a compact design with high torque capabilities, suitable for space-saving applications. It is also noted for its long lifetime due to the absence of grease and its ability to be used in high-temperature environments.
