Question: When should I replace my Treadmill Running Belt?

Answer: As a simple rule, if your Treadmill Belt becomes frayed, curls down or upwards at the sides, ripples down the centre, splits at the join, begins to "Crackle" underfoot, wears thin or will no longer track to the centre then it is time to replace it.

Question: Why should I buy Expert Fitness UK Treadmill Running Belts?

Answer: Unlike many other Treadmill Suppliers throughout the UK, Expert does not sell other peoples Treadmill Belts. Our Belts are factory made for us by a world leader who also supplies many of the Treadmill Manufactures themselves. The only difference between us and the Treadmill Manufacture is we supply our belts with full a 1 Year Warranty. 

Question: Why are your belts not as expensive as the manufacture?

 Answer: We do not have "middle men" nor "sales representatives". Our prices are based on selling good yearly volumes. Our Belts are manufactured and then supplied direct to the leisure club gym owner or service technician at sometimes half the cost of the treadmill manufacture. It is not that our belting is lower priced it is more to the fact that some companies are incredibly greedy!

Question: How do I go about measuring my existing Treadmill Belt?

Method One: Badly Worn Belt > If your belt is so badly worn or damaged and you know it has to be replaced then simply cut across it’s width using a Scissors (do not use a blade as it can scour the deck surface) and remove it from the Treadmill. Lay it on the floor and measure the entire length and width of the belt as close to the mm (millimetre) as possible. Take note also of the position of the Belt Adjusting/Tracking Bolts as if the Belt was badly worn/stretched these bolts will be near maximum tension so you will need to reduce the already measured length (circumference) by 10-20mm.

Method Two: Still Usable Belt > If your belt is not too badly damaged then you can secure a piece of masking tape to the rear side edge of the belt and using a pen draw a line and label it letter (A). Follow the same side towards the front edge of the belt and secure another piece of tape and apply a line and label it (B). Measure between both marks and note it. Now push the belt backwards until the front side letter (B) has moved to the rear and secure another piece of tape again to the front side edge and apply a line and Letter (C). Measure between both marks and make a note. Finally push the belt backwards far enough so you are able to measure between pen mark (C) and pen mark (A). Add measurements (A to B) and (B to C) and (C to A) together. As a guideline reduce the total measurement by the thickness of the belt (X2). Example A-B = 1100mm plus B-C = 1100mm plus C-A 900mm. Total = 3100mm minus belt thickness 3mm (X2) =6mm. So your end measurement will be 3094mm

Method Three: Removed Belt > This is the easiest way to get the most accurate measurement. With the existing Running Belt removed form the machine, ensure the Front Drive Roller is securely in place and then set the Rear Slave Roller in a position based on about half way of the Belt Adjustment bolts (also known as Tension/Tracking bolts). With Rollers in position measure completely around the Front and Rear Rollers for a more accurate measurement.

IMPORTANT: When working out the measurement for your replacement belt using Method Two or Method Three you should always check and note that the position of the Belt Adjusting/Tracking Bolts are positioned half way through their thread as most Treadmills are designed with about 50mm for Tensioning adjustment! If unsure please do give us a call!

We strongly recommend that the re-fitting of New Running Belts is carried out by a Qualified Fitness Equipment Engineer as over-tensioning and under/over Lubrication can Damage the Running Belt before you even step onto the machine. Always ensure that whilst the Deck, Rollers and Belt are removed, the machine gets a good vacuuming and the Rollers cleaned of any Wax or Debris.             The machine should be Spotless before fitting the New Belt!

Question: How do I go about fitting my New Treadmill Belt?

Answer: If you plan on fitting your New Belt yourself here is a simple method that is a lot easier to explain than our Engineers normal method of using Belt stress/strain characteristics.

First, ensure that the surface of your Running Deck is not worn and in good order, check that your Rollers are cleaned of any debris or wax and that the floor is PROPERLY LEVEL. Fit your New Treadmill Belt over the Deck and with the Deck securely fixed then apply a good 40ml application of Expert Oil or an application of Wax Lubrication down the Decks centre (from front to rear). Refit the Front Roller and Rear Roller. Tension both left and right rear belt adjustment bolts EQUALLY CLOCKWISE (a few complete turns) until any slack is removed from the Belt. Refit any remaining side trims etc. Now start the Treadmill up and increase it's speed to about 3kph and take a few steps on the belt. A Simple rule...if it slips underfoot tension both Left and Right adjustment bolts EQUALLY ONE TURN each. Take a few more steps checking for slippage and continue this procedure to the point that the Belt no longer slips. Finally increase the Belt speed a little higher and carefully "Track" the belt to the exact centre of the Running Deck using the LEFT SIDE ADJUSTMENT BOLT ONLY a 1/4 of a turn either way until Belt is centre (To move the belt Right - turn the bolt to the right (Clockwise) and (To move the belt Left - turn the bolt to the left (Anti-Clockwise). Never Fully Tension your Belt in one go from slack and Never adjust both bolts to Track the Belt as it will stretch and pull the Belts fabric out of shape and damage the fabric fibre profile...IF YOUR UNSURE CONSULT A FITNESS EQUIPMENT ENGINEER AND HAVE IT FITTED FOR YOU.

Question: What Treadmill Belt types do you supply?

Answer: We supply 5 types of Treadmill Belt depending on the make and model of your Treadmill. Be wary of suppliers who advise that one belt type or lube will suit all, as you will experience the opposite at your own expense!

Commercial and Home Use Treadmills are designed and built with different motor power ratings usually from 1.5hp to 5.0hp and are fitted with a Running Belt to suit. The thickness and weight of the Running Belt is critical in relation to the specific Drive Unit and Motor fitted and when tensioned enough to eliminate any slippage will also have a direct impact in relation to the load bearing capacity of the front and rear internal roller bearings. Put simply, if a replacement Running Belt is too thick, too heavy or wrongly lubed for a product it will place additional load onto the Motor which, will in turn place additional demand on the Motors Drive System.

Throughout our website we cannot emphasise enough about the right tools for the right job, the correct oil or wax for the right belts and again here the proper belts fitted to their related Treadmills!!!
