Are the drive gears plastic or steel?

The gears are plastic. There should be no issue with corrosion. The only metal part is the axle, which passes through the gearbox to turn it.

The only metal visible are the shafts and handles. From the way it sounds, I'd guess the gears are plastic. Personally, due to history with an old drop spreader and corrosion, I think for this application, plastic is a superior material. Stainless steel? $$$$

The gears are enclosed in a plastic sleeve. I'd guess plastic, but I cannot tell. Do NOT purchase this product until you've read my earlier comments on the opening/closing door not closing!

The ball bearings are ceramic but the races are steel. Fortunately there is no metal to metal contact, thus no chance of rust. These are extremely fast!!!! Very smooth, and impeccably quiet!

Body is metal and the lens are plastic. They are so far working well after several months.

The pulleys are a synthetic material of some sort, probably a phenolic, and seem to be of good quality. Plastic often denotes a cheap product but I don't think this is the case here. It would be a rare bird indeed today to find cast iron drive components in products of this sort.

It is made out of plastic. The only metal parts are the crank and the disks. All of the gears are also made of plastic. The one I purchased worked fine for a few times, but then one of my children cranked too hard and stripped the plastic gears.

Karen: The worm drive is made of 100% hardened carbon steel. The 1st reduction gear is made of POM (Polyoxymethylene) molded onto a hardened carbon steel bushing with a brass insert. The second reduction gear is also made of POM molded onto a hardened carbon steel bushing with a brass insert. The main drive gear is made of 100% hardened carbon steel. POM (Polyoxymethylene) is an engineering polymer that is used in many sizes of precision gears that require high stiffness, high abrasion resistance, high heat resistance, low coefficient of friction and excellent dimensional stability. We used to have all of the gears in our electric meat grinders made of hardened carbon steel, but in 2008 we changed to having both of our reduction gears made out of the POM/steel. By changing these two gears to POM/steel (although they are more expensive than all steel) our grinders can now take a lot more abuse and they also run much smoother and quieter than a gear system made with all steel gears.

They are plastic geared and are controlled by a PWM signal like regular servo motors.

They are plastic. They hold up pretty well but do make a bit of noise going down the sidewalk. The reason for plastic is that it gives the gearboxes some "give" meaning they will slide vs. dig in. This eliminates alot of pressure on the gearboxes.

mine had a steel gear with a plastic bendix drive! same as the original! had to do slight modification to mounting surface were it meets the block to fit totally flat!

Based on the price, and description lacking info on metal tracks I would guess they are plastic. I installed metal tracks and a metal gear box on mine but it is cheaper if you can find one with those options already installed.

Yes, I've popped open the gearbox to replace the spring (for bettr compression and higher fps) the gears and body are metal, the piston is polymer, as well as the guide.

It has very durable steel gears and blades, there is hardly any plastic in this machine. It is VERY powerful and plastic would not hold up to the HP it puts out!!

Purchased this item last year. Mine does not have metal gears. They are plastic , i took the plastic gearbox apart. You wouldn't want metal since they would rust with the water. The body is cast iron and painted so its protected. Well worth the cost for this item.

I believe the handles are aluminum but the gears appear to be reinforced fiber glass. They work very well. I consider them to be a high quality product and am pleased I bought them.

It is chain driven (not belt), so I believe it has metal gears. We were told by a technician that this was one of the best available for an inexpensive price.

i checked both rollers. all metal. i cannot see any plastic on drive or inside rollers. jay

Hello speedgeezer, the handles are plastic and the bearing that the cable spins on is steel. hope this helps.
