Precor 835 Commercial Treadmil, P31 Console, Black

by Precor

The Black Pearl version of the Precor TRM 835 Treadmill combines thoughtful design and performance to deliver an exerciser experience that feels right. The TRM 835 makes it easier for you to provide a customer-focused environment. Quiet and efficient, the streamlined assembly includes diagnostic tools to increase uptime and keep operating costs down. 

The Precor TRM 835 features a 4.0 HP high-efficiency AC-motor drive (8 HP peak) that is optimized with Power Factor Correction (PFC) for increased efficiency, improved performance, and reduced energy consumption by up to 30%, Integrated Footplant Technology that recognizes the exerciser’s natural foot speed and matches every stride for an ultra-smooth feel that enhances the workout experience and Precor's patented Ground Effects® Impact Control System which combines ideal cushioning, support, and stability for exercisers. Precor treadmill decks are designed to absorb more impact in the front where exercisers’ feet hit the belt. Added rigidity at the back of the belt allows for a firm push-off. 

The TRM 835 also comes equipped with the outstanding P31 Console which will allow you to choose from 27 Preset programs accessed directly from 6 buttons, heart rate telemetry reading when using a chest strap (chest strap not included) and an external status light which lets you and your staff know at a glance what the operating condition of your treadmill is and when it needs life-extending maintenance to be performed.

Deck and Belt

Seigling E8 multi-ply polyester belt with optimized lubrication integrated into the material, exclusive to Precor.

The running belt is combined with a pre-waxed deck that offers added lubrication especially during the initial break-in period of the treadmill.

The combination of the exclusive optimized running belt with pre-waxed deck yields a long lasting system. However, when the running belt does need to be replaced and the deck flipped, this service can be completed in less than 20 minutes.

The deck is mounted to the GFX system independent of the frame resulting in a stable, quieter treadmill.

Elevation System

Elevation system generates up to 1000 lbs of thrust and operated in compression for reliable operation.


New frame design results in an ultra-stable console, solid feel, and quiet operation.


Steel tapered rollers keep the belt centered to reduce maintenance and noise.
