BACK
The Rineer 16 Series Roof Bolt Drill Head is a direct Hydraulic motor drive eliminating the inefficiency and high maintenance cost associated with gearbox type drills. This drill head incorporates all the standard features required for drilling and bolting in a single, compact, low profile package. Standard features of this field proven drill head include:
  • 7/8 inch diameter passageway for vacuum suppression
  • Large tapered roller bearings to accommodate thrust and angular loads up to 25,000 pounds
  • Available in Dry suppression only or Wet/Dry models
  • Three suppression ports for ease of mounting and clean out

Constant output torque of the drill head at starting, stall, and running assures that bolt torque repeatability can be attained.

VANE CROSSING VANE
The Rineer patented vane crossing vane design produces much higher volumetric and mechanical efficiencies than is possible with a standard vane type design. This design provides a sealing vane between cavities to improve mechanical and volumetric efficiencies.
STARTING AND STALL TORQUE
The Rineer motor produces torque curves which are virtually flat with starting and stall torque equal to approximately 90-94% of theoretical torque.
SEALS
Buna N seals are supplied as standard on the Rineer motors. Viton seals may be ordered as an option.
FILTRATION
25 micron minimum
FLUID
We suggest premium grade fluids containing high quality rust, oxidation and foam inhibitors, along with anti-wear additives. For best performance, minimum viscosity should be maintained at 100 SSU or higher. Fluid temperature should not exceed 180o F. Elevated fluid temperature will adversely affect seal life while accelerating oxidation and fluid breakdown. Fire resistent fluids may be used with certain limitations. Contact Rineer for additional information.
CASE DRAIN CIRCULATION
Fluid should be circulated through the case when a temperature differential exists between the motor and the system in excess of 50o F. Should this occur, contact a Rineer Application Engineer.
CASE DRAIN AND CROSS PORT LEAKAGE
The combined case drain and cross port leakage of the 16 Series Motor is approximately 1 GPM per 1,000 PSI. This will vary with the oil viscosity and internal clearance selection.
HORSEPOWER LIMITATION
Maximum horsepower limitation may vary with different applications. When using the 16 Series above 175 HP, consult a Rineer Application Engineer.
MOUNTING
The mounting position is unrestricted. The shafts, pilots, and mounting faces should be within .002 TIR.
INTERMITTENT CONDITIONS
Intermittent conditions are to be less than 10% of every minute.
ROTATION
The 16 Series Motor rotates equally well in either direction and smoothly throughout its entire pressure and speed range. Looking into the end of the shaft, rotation is clockwise when oil is supplied to the 3/4" port nearest the chuck.

MORE POWER STROKES PER REVOLUTION
The 16 Series has four stator cavities and 10 rotor vanes. Each rotor vane works in each stator cavity once per revolution, which results in 40 power strokes per revolution. This helps produce higher mechanical efficiency and flatter torque curves.
SLINGER
The Roof Bolt Drill Head uses a slinger to retain the replaceable chuck and provide a labyrinth seal to protect the top seal plate from direct assault by drilling debris. The slinger is attached to the motor shaft with a right hand thread.
CHUCKS
A replaceable chuck is supplied with 1-1/8" hex x 1" deep, and 1" square by 1" deep.
DUST SUPPRESSION
The 16 series -14 version is designed for dry (vacuum) dust suppression system applications. The 16 series -18 version can be used for dry (vacuum) dust suppression or wet dust suppression systems interchangeably.
SUPPRESSION PORTS
The Rineer Drill Head is provided with two 1-1/4" NPT suppression ports located 180 degrees apart.
CLEAN OUT PORT
The bottom of the drill head contains a 1" NPT pipe plug which can easily be removed for cleaning or may be used as an optional suppression port.
PASSAGEWAY
Below the chuck is a 7/8" diameter passageway which communicates to all three suppression ports.
SEAL PLATES
The drill head has two removable shaft seal plates. The top seal plate is located beneath the slinger and is held in place by four socket head cap screws. The second seal plate is located on the bottom of the motor and held in place by an internal type snap ring. Either seal plate can be easily removed if seal replacement is ever required.
LUBRICATION
All bearings are immersed in hydraulic oil which is continuously circulated as the motor rotates, eliminating the manual periodic lubrication required by gearbox type drill heads. Wet application versions require periodic greasing at a supplied fitting for seal lubrication.
MINE SAFETY
The Rineer Roof Bolt Drill Heads have been approved by the Mine Safety and Health Administration as components of integral dust collecting systems meeting the requirements of MSHA 30 CFR part 33.
