Specifications:
The document provides detailed specifications for various types of SY SLR-CS roller chains, including dimensions such as pitch, roller diameter, pin diameter, plate length, height, and thickness. It also lists the average tensile strength and chain weight for each type.

Chain Types and Dimensions:
- SY 40-1 SLR-CS: Pitch 12.70 mm, Roller Dia. 7.95 mm, Average Tensile Strength 15.70 KN, Weight 0.6 kg/m.
- SY 50-1 SLR-CS: Pitch 15.875 mm, Roller Dia. 9.53 mm, Average Tensile Strength 25.50 KN, Weight 1.0 kg/m.
- SY 60-1 SLR-CS: Pitch 19.05 mm, Roller Dia. 12.70 mm, Average Tensile Strength 37.30 KN, Weight 1.5 kg/m.
- SY 80-1 SLR-CS: Pitch 25.40 mm, Roller Dia. 15.88 mm, Average Tensile Strength 63.70 KN, Weight 2.5 kg/m.
- SY 100-1 SLR-CS: Pitch 31.75 mm, Roller Dia. 19.05 mm, Average Tensile Strength 100.00 KN, Weight 3.9 kg/m.
- SY 120-1 SLR-CS: Pitch 38.10 mm, Roller Dia. 25.40 mm, Average Tensile Strength 157.00 KN, Weight 5.8 kg/m.

Design and Usage:
The SLR-CS type strand chains are designed for use with standard sprockets and feature cotter-style connecting links for sizes above 100 SLR-CS. They are not suitable for environments exposed to chemicals, water, or shock loads.

Lubrication and Maintenance:
The chains are equipped with oil-impregnated bushings that provide lubrication to critical areas. However, the lubricant may deplete rapidly at temperatures above 70℃ or in wet/dusty environments, leading to reduced service life.

Additional Features:
The chains are black-oxide coated for extra protection and are pre-lubricated before delivery. They are specifically designed for conveyor applications, carrying their own high-quality lubricant within the impregnated bushing.
