Ruland Manufacturing Hubs Indonesia

 

Ruland jaw coupling hubs are machined with a precise curved jaw profile that press-fits with the spider for zero-backlash performance. This design concentrates forces on the spider’s limbs, improving damping and overall durability.

Jaw couplings are considered fail-safe because if the jaw coupling spider fails, the interlocking hubs maintain power transmission long enough for a safe shutdown and maintenance

Ruland One-piece rigid couplings Indonesia

 

  • One-piece rigid couplings from Ruland do not mar the shaft and have high torsional holding power. They are supplied with proprietary Nypatch® anti-vibration coating, which allows for repeated installations, prevents screws from coming loose during operation, and provides the necessary dissimilar material in stainless steel couplings to reduce galling. Straight bore rigid couplings from Ruland are precision honed to ensure bores are collinear. This is important when the rigid coupling is used in a precision servo system as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures one-piece rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and lightweight 2024 aluminum

Ruland Friction Bearing Indonesia

 

  • Ruland friction-bearing universal joints (also called cardan joints) are built for moderate-to-high torque applications across many industries. Made from alloy steel for strength or stainless steel for corrosion resistance, each u-joint is precision-machined and ground for long-lasting performance.

    Single u-joints fit tight spaces and handle up to 45° of angular misalignment, while double u-joints handle larger shaft distances and up to 90° of misalignment.

    Available in OD sizes from 3/8”–3” and bore sizes from 3/16”–1 1/2” (5mm–35mm), Ruland universal joints can be ordered with or without keyways, machinable bores, and set screws for custom configurations. They are manufactured by Belden Universal and rebored, keyed, and set screwed or clamped by Ruland

Eighty years is a long time to be in business, and at Ruland we are proud to have reached that milestone in 2017. It all began in 1937 when 20 year old Fred F. Ruland bought two screw machines at a junkyard for $50 each and merged the parts into a working unit. He ran the machine during the day in a loft of a textile mill at 40 Pleasant Street in Watertown, Massachusetts, which he rented for $20 per month. At night he worked at the Waltham Watch Company to pay the bills.

Soon thereafter, World War II loomed and the business became a full time job. By the time of Pearl Harbor in late 1941, there were 20 employees on three shifts. Military work included spring rings for .50 caliber machine guns and clamp-style shaft collars for bombsights and guidance instruments.

Fred F. Ruland found tremendous satisfaction working to close tolerances and providing value added design work. This led to a reputation for innovation and precision along with many proprietary processes and patents.

After the war, all government work ceased and Ruland Manufacturing turned to civilian products, such as tire pumps, in an effort to survive while other "war babies" became business failures.

Survive the Company did, but the emphasis was soon back to precision products. One such specialty was high pressure valves used in aerospace applications. This led to a proud moment when a Ruland valve pressurized the spacesuit of the first American to walk in space.
