NEMA 34 86mm Precision Planetary Reducer Heavy Duty Industrial High Torque

NEMA 34 86mm Precision Planetary Reducer | Heavy-duty Industrial High Torque, High-precision Stable Drive Transmission Core

Core Advantages

• Industrial Precision Grinding & Ultra-low Backlash The core gears are made of high-quality 20CrMnTi alloy, finely processed through multiple carburizing, quenching hardening and precision five-axis gear grinding technology, featuring high tooth surface hardness, accurate tooth profile and tight uniform meshing. Single-stage backlash ≤5 arcmin and double-stage backlash ≤8 arcmin, completely eliminating transmission clearance and positioning deviation with excellent repeated positioning accuracy. It fully meets the strict precision requirements of CNC equipment, precision tooling and high-precision processing equipment for micro-feeding, accurate alignment and constant-speed stable transmission.
• Heavy-duty Reinforced Structure & Super High Torque Capacity Equipped with widened and thickened tooth surfaces, integrated thickened planetary carrier and multi-tooth uniform load transmission structure, the overall rigidity, deformation resistance and impact resistance are greatly upgraded with uniform force distribution and low loss. The maximum output torque reaches 120N·m, with far higher load capacity than ordinary reducers of the same specification. It easily adapts to complex heavy-duty working conditions such as long-term full load, impact load, variable frequency speed regulation and high-frequency start-stop, maintaining stable operation without stalling, deformation or jitter during continuous heavy-load operation.
• High-efficiency Silent Transmission & All-weather Ultra Durability The optimized high-precision involute tooth profile ensures smooth gear meshing with minimal transmission loss. The full-load operating noise is ≤48dB, delivering stable and quiet operation without abnormal noise at both high and low speeds. The maximum transmission efficiency reaches 98% with high power utilization and outstanding energy-saving performance. Equipped with an industrial-grade fully sealed dustproof and waterproof structure, high-wear precision bearings and high-temperature resistant long-life grease, it works stably in a wide temperature range of -20℃~+90℃. With excellent corrosion resistance, aging resistance and wear resistance, its service life reaches 20,000 hours, effectively reducing equipment downtime and maintenance costs.
• Full-range Gear Ratio Coverage & Ultra-high Universal Compatibility Adopts a modular combined design with complete gear ratio specifications: 1-stage (3.7/5.2/10), 2-stage (15~50), 3-stage (60~200), fully covering working conditions of high-speed precision control, medium-speed stable transmission and low-speed heavy load. Standard universal flange mounting holes enable easy disassembly and assembly with strong compatibility. It can directly replace mainstream 86-series industrial reducers on the market, suitable for complete machine matching and renovation upgrading of various heavy-duty automation equipment.
