Features

True Helical Gear Design
Precision helical gearing increases tooth to tooth contact ratio by over 33% vs spur gearing. The helix angle produces smooth and quiet operation with decreased backlash (less than 1 arc-minutes and ≤ 56dB).

Triple split collet with dynamic balanced set collar clamping system
Provides backlash free power transmission and eliminates slippage. 100% concentricity allows for smooth rotation and higher input speed capability.

Bushing module system design
The unique motor adapter and bushing module system design allows for quick and easy mounting of any motor.

A special non-electrolysis Nickel surface treatment
A special non-electrolysis nickel surface treatment on the output housing and black anodized aluminum input adapter are provided for the most extreme environmental conditions.

Single piece structured ring gear with housing
Helical Internal ring gear is machined directly into a single piece of steel. Maximized diameter and number of teeth to improve overall performance and torque capacity.

NYOGEL 792D
Lubricated with Nyogel 792D synthetic grease (Smart Grease) and sealed to IP65 standards prevent leakage and is maintenance free.

Whole piece planet carrier design
One piece planet carrier with extended bearing design provides maximum radial load capacity and increases system reliability and stiffness.

In-house plasma nitriding heat treatment
Our in house plasma nitriding heat treatment process maintains the tooth surface hardness at 900Hv for superior wear-resistance and a core hardness at 30HRc for toughness.

HeliTopo technology
A high setting gear performance is achieved by using our HeliTopo Technology. This eases off the tooth profile and crowns the lead of each tooth. This optimizes the gear mesh alignment and overlap to achieve maximum tooth surface contact.

Solid needle roller bearings without cage
Equipped with solid uncaged needle roller bearings, provides maximum contact points to increase stiffness and generates high output torque.

NEW - Patented Output sealing system design
NEW - Patented output sealing systems design eliminates friction and heat generation which is accomplished by applying our hi-tech coating to all output contact surfaces. This coating reaches a hardness of 3700Hv and is ground to Ra 0.2mm finish to ensure sealing.

NEW - Patented input sealing system design
NEW - Patented input sealing system design eliminates break away torque and decreases friction/heat. The hi-tech coating bushing (3700 Hv, Ra 0.2 mm finish) interfaces with our proprietory seal which decreases wear and erosion of both sealing surfaces. This new patent prevents leakage and has a service life of over 20,000 hours.

Patented planet carrier design
Patented planet carrier design puts the sun gear bearing directly into the planet carrier. It minimizes gear misalignment to gain higher accuracy.

Solid,Single piece sun gear construction obtains precise concentricity with increased strength and rigidity.
