SP Series Heavy Duty Roller Chain High Strength Short Pitch

Heavy Duty Roller Chains are manufactured to ANSI B29.1 Standards but feature thicker side plates. Having thicker side plates not only drastically increases the strength and fatigue resistance of a roller chain, but it also reduces stretching and wear that happens over time. Heavy-duty roller chains are optimal to use in agricultural applications, skid steers, heavy equipment, and any application that you are looking to increase the strength of the chain without having to go up a size. HZPT has the widest selection of heavy chains, standardly we stock simplex, duplex, triplex, double pitch, and even cottered heavy roller chain.

Heavy Duty Roller Chain lubrication

Like bearings need grease, heavy duty roller chains need lubricant. At HZPT we have the largest selection of heavy duty roller chain oil lubricants and lubrication systems. Ranging from food-grade, high-temp, low-temp, and even dry we're sure to have the heavy duty roller chain lubricant for your application. Proper heavy duty roller chain lubricating not only improves the life of the chain, but it also improves sprocket life and reduces noise and shock loads. Lubrication can increase the life and performance of any heavy duty roller chain, regardless of chain grade/ quality level ann material. The lubricant types that we supply are specially formulated for industrial and manufacturing uses, and they are all proven performers in the industry.

Heavy Duty Roller Chain Lubrication Placement

Proper placement of lubricant is essential for obtaining the optimal life out of your heavy duty roller chain and lubricant.

  • A - Apply heavy duty roller chain lubricant between the roller and inner side plate, this disperses the lube between the roller and bushing.
  • B - Apply Apply heavy duty roller chain lubricant between the inner and outer side plates to lubricate the plates where they contact each other and the pin for an optimal pin-on-bushing contact.

Heavy Duty Roller Chain Lubrication Placement

Heavy-Duty Roller Chain Sprockets

Besides roller chain, we can also supply sprockets. When using a sprocket that has less than 30 teeth for a heavy roller chain, it is recommended that the sprocket has hardened teeth. All of the sprockets we supply with 30 teeth or less come with hardened teeth as a standard.

Single-strand heavy-duty roller chain is compatible with standard sprockets. We keep a full line of ANSI sprockets in stock in a wide range of variations, including taper bushed and QD style.

Multi-strand heavy-duty roller chain sprockets and standard multi-strand roller chain sprockets are not interchangeable. The reasoning is that the thicker side plates on the chain will not allow for the roller chain to seat and engage properly with a standard double sprocket. We can supply specially manufactured sprockets for this chain, but it will require a 1 - 3 week manufacturing lead time.

Heavy Duty Roller Chain Manufacturers

Heavy duty roller chain is a crucial component in many types of industrial equipment. We are proud to offer the best and strongest heavy duty roller chains in the business. Our lineup of standard roller chains include the most common chain sizes and types in the industry. These chains conform to ANSI B29.1 Standards and are manufactured from high-quality carbon steel. For more information or pricing simply contact us or select the subcategories below.

We typically supply #50, #60, #80 and #100 standard duty roller chains for agricultural applications. We also supply #50H, #60H, #80H and #100H heavy duty roller chains for the toughest applications that need the longest life out of their chain. Due to the high speed nature of agriculture equipment chains, we recommend using our Heavy Duty, Solid Rollers, and Solid Bushing quality roller chains that is specifically made for high speed applications. The pins of this chain are case hardened and have the highest outside rockwell hardness across all three quality levels, along with heat-treated bushings, rollers, and side-plates. Having a harder pin will eliminate stretch for most pieces of equipment. Along with the heat treated pins, rollers, and side-plates, all heavy duty roller chains are pre-stretched at the factory. Without excessive chain stretch, you have substantially less wear on the components and the chain will last longer. We offer all our precision roller chain in 10’ coils, 50’ and 100’ reels. please contact us today.

FAQ

Q1: What is the strongest roller chain?
A: Roller chains are made according to the impact force of the load to be operated. Going by the average tensile strength and weight-to-strength ratio, the 200HR ANSI Standard Heavy Series roller chain is the strongest at 113,759 lbs and 12.835 lbs per ft.

Q2: What is a Heavy Series roller chain?
A: Heavy Series roller chains have thicker link plates, despite being ANSI B29.1 standard. The inner and outer link plates are thickened so that the chains can endure more demanding working conditions, are less prone to wear and tears and have improved resistance to fatigue.

Q3: What is a heavy roller chain?
A: Heavy Duty Roller Chains are chains capable of pulling huge loads, working under impact-filled conditions, construction equipment, oil rigs and drills and amusement park structures.

Q4: How strong is the #40 Heavy Roller Chain?
A: The #40 heavy roller chains are made under the most precise conditions and with specific materials. Rollers are modeled using high-tensile steel alloys and ANSI standard dimensions, putting the chain’s tensile strength at 3,700 lbs. These chains also have a pound-for-pound strength that is almost unrivaled, with a weight-to-strength ratio of 0.41 lbs/ft.
