812481 Gear Reducer SK871.1Z 7.18:1, 210TC

The 812481 Gear Reducer by Blackmer is a 7.18:1 ratio reducer with a 210TC motor frame interface, designed to optimize pump performance and reliability.

This gear reducer features a durable construction with high-strength steel gears and precise machining for consistent power transmission. The gearing is resistant to corrosion and wear, ensuring long service life in demanding environments. It has overall dimensions compatible with industry-standard applications requiring a 210TC interface, with input shaft diameters and keyways specified for secure attachment.

Dimensions include an output shaft length of approximately 8 inches, a width of 6 inches, and a height of 5 inches, with a weight of around 12 kilograms. The reduction ratio of 7.18:1 effectively decreases input speed while increasing torque, making it suitable for various pump configurations. The unit's mounting flange aligns with industry standards, and it is compatible with motors and pumps that utilize a 210TC frame and matching shaft specifications.

Key features of the 812481 Gear Reducer include a cast iron housing for durability, an oil bath lubrication system for smooth operation, sealed bearings to prevent ingress of contaminants, and a straightforward mounting pattern suitable for positive displacement and sliding vane pump applications. Its design facilitates easy installation, maintenance, and replacement, with a mounting pattern optimized for quick setup.

Primarily, the 812481 Gear Reducer is ideal for applications involving pumping, industrial fluid transfer, or manufacturing processes where precise speed control and torque are critical. It is suitable for engineers and technicians seeking a reliable, cost-effective solution that enhances pump efficiency. This gear reducer is especially beneficial for systems with tight space constraints or requiring robust heavy-duty performance, and it accommodates budget-conscious operations without sacrificing durability.

The product ships with the gear reducer unit only; compatible mounting hardware, lubricants, and motor coupling are not included and must be purchased separately. Prior to installation, verify motor and pump compatibility, ensure correct alignment, and fill the unit with manufacturer-recommended lubricant. Maintenance includes regular oil checks, seal inspections, and periodic re-alignment to maintain optimal performance.

Ensure proper operation by following the manufacturer's care instructions, including checking lubrication levels, replacing seals when needed, and operating within specified load and speed limits. The 812481 Gear Reducer is designed for long-term use with minimal maintenance, providing dependable performance in industrial environments.
