The 4720002952 Tension Cylinder Tensioner is a hydraulic component designed exclusively for the F141C series of tracked machinery (e.g., crawler excavators, forestry harvesters). Its core function is to maintain consistent tension in the machine’s track system—preventing track slack (which causes slippage) or over-tension (which damages track chains and bearings). Produced by JST with hydraulic engineering expertise, it replaces aging tensioners that lead to uneven track wear, reduced fuel efficiency, or sudden track detachment during heavy work.
The F141C operates in challenging terrains, and the 4720002952 tensioner solves two key issues:
In rocky mines or forested areas, the F141C’s tracks frequently hit obstacles, causing tension fluctuations. Low-quality tensioners fail to adjust quickly, leading to track slack and slippage. The 4720002952 tensioner uses a high-speed hydraulic valve that adjusts tension within 0.5 seconds—keeping the track tight even when navigating bumps or slopes. This ensures the machine maintains traction, avoiding delays in mining or logging operations.
In regions with temperatures below -10℃, standard hydraulic tensioners often suffer from oil thickening—slowing tension adjustment or causing valve blockages. The 4720002952 tensioner uses low-temperature hydraulic oil (viscosity grade ISO VG 32) that remains fluid at -30℃. It also features a built-in heater (activated when temperature drops below -5℃) to keep oil flowing smoothly—critical for winter road construction or Arctic mining.
• High-Pressure Resistance: The cylinder body is made of 27SiMn alloy steel (heat-treated to 800MPa compressive strength), withstanding working pressures up to 30MPa (no deformation or leakage).
• Seal Reliability: Uses imported NBR rubber seals (oil-resistant and low-temperature resistant) that prevent hydraulic oil leakage—extending the tensioner’s maintenance interval to 2,000+ hours.
• Automatic Tension Adjustment: Equipped with a pressure relief valve that prevents over-tensioning, protecting the track chain and bearings from damage.
• Model Compatibility: Exclusively fits F141C series tracked machinery (e.g., F141C Crawler Excavator, F141C Forestry Harvester).
• Cylinder Specifications: 50mm bore diameter × 120mm stroke (provides sufficient tension adjustment for F141C’s 1.8m-wide tracks).
• Working Pressure: 20-30MPa (adjustable via the machine’s hydraulic control system).
• Hydraulic Oil Type: ISO VG 32 low-temperature hydraulic oil (compatible with F141C’s hydraulic system).
• Weight: 3.5kg (balances strength and machine load).
• Protection Rating: IP65 (dustproof and water-resistant, suitable for outdoor and low-temperature use).
• Hydraulic System Testing: We offer free testing of the F141C’s hydraulic system to ensure compatibility with the 4720002952 tensioner. Our engineers can also optimize the system’s pressure settings for maximum performance.
• Warranty: 20-month warranty. If the tensioner leaks or fails to adjust tension, we provide free replacement and cover shipping costs.
• Maintenance Training: For fleet owners, we conduct online or on-site training on tensioner maintenance (e.g., oil replacement, seal inspection) to extend the component’s lifespan.
